&lt;hr /&gt;
&lt;div&gt;A '''cave-in''' can occur if an area is detached from all supporting tiles. A room can be as large as you want to make it, as long as it is supported by at least one tile from below. The system is a bit buggy right now, since it is only a placeholder.{{version|0.27.169.33a}} Toady has stated he intends to implement more realistic cave-ins in future versions.&lt;br /&gt;
&lt;br /&gt;
Cave-ins can be disabled through the [[Technical tricks|init]] file, by changing [CAVEINS:YES] to [CAVEINS:NO].&lt;br /&gt;
&lt;br /&gt;
== How cave-ins work ==&lt;br /&gt;
&lt;br /&gt;
Any ''unconnected'' section of rock (rock that is completely isolated from the rest of the world) will cave in. The game checks for rock connections along the X, Y, and Z axes (that's left/right, up/down, and high/low). Diagonal connections are not taken into account yet. Stairs and supports count as supports for the rock.&lt;br /&gt;
&lt;br /&gt;
== Results of a cave-in ==&lt;br /&gt;
&lt;br /&gt;
* Any [[creature]] caught under the falling material is crushed and killed.&lt;br /&gt;
* Any item caught under the falling material is [[encased]] in stone and must be dug out.&lt;br /&gt;
* Obviously, anything standing -on- the area that caves in falls and may be wounded.&lt;br /&gt;
* A large amount of dust is generated; Any creature caught by the dust from the collapse is knocked [[unconscious]], and may recieve [[Wounds|injuries]]&lt;br /&gt;
* All [[building]]s and [[construction]]s under and above the falling area are destroyed&lt;br /&gt;
* [[Rock]] remains mostly intact, while [[wood]] constructions become logs&lt;br /&gt;
* Unmined rock and soil crashes through multiple [[floor]]s, and stops only upon reaching solid ground, where it piles up&lt;br /&gt;
* Mined stairs and ramps will settle like unmined rock; Stairs down that fall onto previously empty floors will reveal the level below. If there's rock or floor above them, it'll cover the stairs.&lt;br /&gt;
* Anything falling into a flow (like [[water]]) sinks to the bottom{{ver|0.27.169.33a}}&lt;br /&gt;
&lt;br /&gt;
== Avoiding cave-ins ==&lt;br /&gt;
&lt;br /&gt;
Do not make unconnected sections of rock.&lt;br /&gt;
&lt;br /&gt;
Actually, you're quite unlikely to cause cave-ins unless you are actively trying to cause them. In which case, you'd be wondering how to avoid cave-ins that ''cause damage'' to your folks. That's simple: Add a support under the stone mass, and link it to a distant lever. When you're done, hide everyone, pull the lever and watch the fireworks.&lt;br /&gt;
&lt;br /&gt;
One of the more common accidental cave-ins results when you're taking out the floor in a checker-pattern and the area below isn't supported, resulting in a situation like the diagram below:&lt;br /&gt;
&lt;br /&gt;
 Floor -1&lt;br /&gt;

&lt;div&gt;I've had a chasm in a mountainous area near a volcano which was in fact cylindrical, not shaped like a river at all. It was basically a bore of empty space all the way to the bottom-most level, which consisted of the # chasm squares. In that respect, it looked much like a volcano bore but generally a bit smaller. There were variations in width on different levels of it as well. This led to open cave floor around it on some levels where troglodytes, iron men, giant cave swallows, and caveswallowmen frolicked about. --[[User:Janus|Janus]] 08:25, 1 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
:Huh, how about that.  They're certainly more interesting than they used to be.--[[User:Draco18s|Draco18s]] 14:54, 1 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
:Interesting. Sounds like a magma vent minus the magma. I have a game going in a grassland a few region squares away from a volcano. When I first started the game, I got a message that part of the cavern had collapsed and it zoomed to the magma vent. The vent itself was as you describe--a roughly cylindrical sinkhole of varying widths that went all the way to the bottom. Only in my case, it was full of magma up to the surface, and at lower depths, fire imps, magma men and fire snakes could be seen (Apparently, magma is transparent.) Maybe the game treats magma vents as localized chasms full of magma? --[[User:RedKing|RedKing]] 16:43, 3 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
:: That's probably how it was formed, using the same algorithm as a magma vent, but it does appear to be intentional. Perhaps it is indeed meant to be a dead magma vent. That same map has the main volcano magma vent a short distance away. The magma vent was of course shown on the local map when choosing the map location, but the circular chasm was not.&lt;br /&gt;
::As for the collapse message when starting on a map with a magma vent, that appears to be due to a bug where a body of water is generated in the middle of it. This water instantly creates a solid block of obsidian with no support, which then collapses. Magma is semi-liquid, and fireproof monsters like those you mention will swim freely through it. --[[User:Janus|Janus]] 17:06, 3 November 2007 (EDT)&lt;br /&gt;
&lt;br /&gt;
Actually there are two variants of the chasm, a chasm vent/pit and a chasm/river star like chasm (encountered this one twice, and it really fucked up the level). Perhaps we should works this into the article. Perhaps we should ad screenshots. I sadly have no save with the star river like chasm anymore (abandoned those). --[[User:Soyweiser|Soyweiser]] 18:45, 7 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
I'm playing a fortress right now with the same type of &amp;quot;pit&amp;quot; chasm.  I'll see if I can get a shot of it to add to the page. --[[User:Sk128234|Sk128234]] 19:08, 7 November 2007 (EST)&lt;br /&gt;
&lt;br /&gt;
Are the surface chasms visible from the map when selecting the site? It would be great to get a screenshot of that for the page to look similarly to the volcano page. --[[User:JPolito|JPolito]] 02:26, 18 November 2007 (EST)&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;A '''cave-in''' can occur if an area is detached from all supporting tiles. A room can be as large as you want to make it, as long as it is supported by at least one tile from below. The system is a bit buggy right now, since it is only a placeholder.{{version|0.27.169.33a}} Toady has stated he intends to implement more realistic cave-ins in future versions.&lt;br /&gt;
&lt;br /&gt;
Cave-ins can be disabled through the [[Technical tricks|init]] file, by changing [CAVEINS:YES] to [CAVEINS:NO].&lt;br /&gt;
&lt;br /&gt;
== How cave-ins work ==&lt;br /&gt;
&lt;br /&gt;
Any ''unconnected'' section of rock (rock that is completely isolated from the rest of the world) will cave in. The game checks for rock connections along the X, Y, and Z axes (that's left/right, up/down, and high/low). Diagonal connections are not taken into account yet. Stairs and supports count as supports for the rock.&lt;br /&gt;
&lt;br /&gt;
== Results of a cave-in ==&lt;br /&gt;
&lt;br /&gt;
* Any [[creature]] caught under the falling material is crushed and killed.&lt;br /&gt;
* Any item caught under the falling material is [[encased]] in stone and must be dug out.&lt;br /&gt;
* Obviously, anything standing -on- the area that caves in falls and may be wounded.&lt;br /&gt;
* A large amount of dust is generated; Any creature caught by the dust from the collapse is knocked [[unconscious]], and may recieve [[Wounds|injuries]]&lt;br /&gt;
* All [[building]]s and [[construction]]s under and above the falling area are destroyed&lt;br /&gt;
* [[Rock]] remains mostly intact, while [[wood]] constructions become logs&lt;br /&gt;
* Unmined rock and soil crashes through multiple [[floor]]s, and stops only upon reaching solid ground, where it piles up&lt;br /&gt;
* Mined stairs and ramps will settle like unmined rock; Stairs down that fall onto previously empty floors will reveal the level below&lt;br /&gt;
* Anything falling into a [[flow]] (like [[water]]) sinks to the bottom{{ver|0.27.169.33a}}&lt;br /&gt;
&lt;br /&gt;
== Avoiding cave-ins ==&lt;br /&gt;
&lt;br /&gt;
Do not make unconnected sections of rock.&lt;br /&gt;
&lt;br /&gt;
Actually, you're quite unlikely to cause cave-ins unless you are actively trying to cause them. In which case, you'd be wondering how to avoid cave-ins that ''cause damage'' to your folks. That's simple: Add a support under the stone mass, and link it to a distant lever. When you're done, hide everyone, pull the lever and watch the fireworks.&lt;br /&gt;
&lt;br /&gt;
One of the more common accidental cave-ins results when you're taking out the floor in a checker-pattern and the area below isn't supported, resulting in a situation like the diagram below:&lt;br /&gt;
&lt;br /&gt;
 Floor -1&lt;br /&gt;
 ▒▒▒▒▒▒&lt;br /&gt;
 ▒    ▒&lt;br /&gt;
 ▒ X +▒ &amp;lt;-- The X is a floor tile. It's not attached, so it will fall down.&lt;br /&gt;
 ▒  +&amp;gt;▒&lt;br /&gt;
 ▒    ▒&lt;br /&gt;
 ▒▒▒▒▒▒&lt;br /&gt;
 &lt;br /&gt;
 Floor -2&lt;br /&gt;
 ▒▒▒▒▒▒&lt;br /&gt;
 ▒....▒&lt;br /&gt;
 ▒...▒▒ &amp;lt;-- Causing this area to receive a cave-in flow and knocking out any dwarves in its reach.&lt;br /&gt;
 ▒...&amp;lt;▒&lt;br /&gt;
 ▒....▒&lt;br /&gt;
 ▒▒▒▒▒▒&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;== Surface Rivers ==&lt;br /&gt;
&lt;br /&gt;
Rivers are found on the surface of world maps. They vary in width and depth, some being more wide and some being more deep than others. They often flow through deep canyons or just across the flat surface of a level. On levels with cliffs, [[waterfall|waterfalls]] may be found. [[Brook]]s are more shallow than rivers and can be crossed by creatures and dwarves without a bridge.&lt;br /&gt;
&lt;br /&gt;
'''Major rivers, Minor rivers and Brooks'''''&lt;br /&gt;
&lt;br /&gt;
On the surface of the world you can find three different types of rivers. &lt;br /&gt;
&lt;br /&gt;
*Major Rivers are distinguished by a different symbol than just a &amp;quot;-&amp;quot; instead they are an &amp;quot;=&amp;quot; some worlds have no Major Rivers so they can be considered quite valuable. Usually they have minor river tributaries and can often feed large lakes. The difference (if any) between major and minor rivers has yet to be discovered. However major rivers are beleived to lower the fps/&lt;br /&gt;
&lt;br /&gt;
*Minor Rivers are dark blue and usually have tributaries of brooks.&lt;br /&gt;
&lt;br /&gt;
*Brooks are light blue and come from springs.&lt;br /&gt;
&lt;br /&gt;
[[Image:Watersystems01.jpg|298px|thumb|Different sorts of rivers in action]]&lt;br /&gt;
&lt;br /&gt;
== Underground Rivers ==&lt;br /&gt;
&lt;br /&gt;
An underground river is, obviously, a river found underground. They are hard to find in the current version of Dwarf Fortress, particularly because you are not guaranteed to have one in your map.&lt;br /&gt;
&lt;br /&gt;
If you are lucky enough to find a cave river, you can use it as the basis of an [[underground forest]] operation.&lt;br /&gt;
&lt;br /&gt;
== Other Important Facts ==&lt;br /&gt;
&lt;br /&gt;
*Rivers presumably contain an unlimited amount of water and cannot be drained.&lt;br /&gt;
*Rivers often contain an abundance of [[fishing|fish]].&lt;br /&gt;
*See [[water]].&lt;br /&gt;

		<summary type="html">&lt;p&gt;JPolito: /* Bone supply(?) */ Fixed errors&lt;/p&gt;
&lt;hr /&gt;
&lt;div&gt;Chasms appear similarly to rivers, but are not visible on the Local/Region/World maps.  They are similar to the DFv0.23 chasms except that they are not guaranteed, seem to use the same river-generation code for the fortress map (a &amp;quot;chasm tributary&amp;quot; has been observed), and occupy all depths.&lt;br /&gt;
&lt;br /&gt;
Chasms are much more common on named [[mountain]]s and [[volcano]]es, along with other special features such as [[cave river]]s.&lt;br /&gt;
&lt;br /&gt;
Chasms are possibly the only feature that can create Extreme Cliffs (20+) that may be observed on the Local Map.&lt;br /&gt;
&lt;br /&gt;
Chasms can also appear in a rounded shape, as below:&lt;br /&gt;
&lt;br /&gt;
[[Image:chasm.PNG]]&lt;br /&gt;
&lt;br /&gt;
== Uses ==&lt;br /&gt;
These uses are meant to be used with the lowermost level of the chasm. (Where you can see no lower)&lt;br /&gt;
&lt;br /&gt;
=== Platform-chasming ===&lt;br /&gt;
A technique of building a platform over the chasm, and then severing the platform from the wall, can permanently dispose of garbage or excess stone set on top. The severed platform will disappear into the darkness below, and never be seen ever again.&lt;br /&gt;
&lt;br /&gt;
=== Garbage dump ===&lt;br /&gt;
It may still be possible to chasm refuse as it was in earlier versions. Try designating a garbage dump [[activity zone]] over the chasm. Monsters may also spring from the chasm, and were provoked by the chasming of refuse in previous versions. It is unknown if these events still occur. Given that this technique still works, you can dump anything in your fortress by selecting {{key|k}} and marking items for {{key|d}}umping.&lt;br /&gt;
&lt;br /&gt;
=== Bone supply(?) ===&lt;br /&gt;
''Needs confirming - based on older version technique''&amp;lt;br/&amp;gt;&lt;br /&gt;
Monsters will spring from the chasm on some occasions. Provoking these attacks and dealing with the monsters on a regular basis makes a nice bone supply. Chasm creatures also present excellent training opportunities for military dwarves.&lt;br /&gt;
&lt;br /&gt;
== Hazards ==&lt;br /&gt;
&lt;br /&gt;
Dwarves fighting near the edges of cliffs have a propensity to dodge right off the precipice, falling to their deaths.&lt;br /&gt;
&lt;br /&gt;
The chasm is also home to many types of hostile creatures, including [[iron men]], [[giant cave swallow]]s, [[antmen]], [[giant cave spider]]s, and [[ratmen]].&lt;br /&gt;

&lt;div&gt;== Surface Rivers ==&lt;br /&gt;
&lt;br /&gt;
Rivers are found on the surface of world maps. They vary in width and depth, some being more wide and some being more deep than others. They often flow through deep canyons or just across the flat surface of a level. On levels with cliffs, [[waterfall|waterfalls]] may be found. [[Brook]]s are more shallow than rivers and can be crossed by creatures and dwarves without a bridge.&lt;br /&gt;
&lt;br /&gt;
== Underground Rivers ==&lt;br /&gt;
&lt;br /&gt;
A cave river is, obviously, a river found underground. They are hard to find in the current version of Dwarf Fortress, particularly because you are not guaranteed to have one in your map.&lt;br /&gt;
&lt;br /&gt;
If you are lucky enough to find a cave river, you can use it as the basis of an [[underground forest]] operation.&lt;br /&gt;
&lt;br /&gt;
== Other Important Facts ==&lt;br /&gt;
&lt;br /&gt;
*Rivers presumably contain an unlimited amount of water and cannot be drained.&lt;br /&gt;
*Rivers often contain an abundance of [[fishing|fish]].&lt;br /&gt;
*See [[water]].&lt;br /&gt;

&lt;div&gt;In general, there are two types of lakes.&lt;br /&gt;
&lt;br /&gt;
== Surface Lakes ==&lt;br /&gt;
&lt;br /&gt;
Freshwater lakes can be found covering vast areas of land on certain world maps.&lt;br /&gt;
&lt;br /&gt;
== Underground Lakes ==&lt;br /&gt;
&lt;br /&gt;
Underground lakes can be found buried in mountains. They are about the size of a magma chamber but only two or three levels deep.&lt;br /&gt;
&lt;br /&gt;
Underground lakes offer a fine habitat for various dangerous creatures, including:&lt;br /&gt;
&lt;br /&gt;
*Olmen&lt;br /&gt;
*Cave Crocodiles&lt;br /&gt;
*Frogmen&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;A '''volcano''' is a vent in the planet's crust through which lava and pyroclastic materials are expelled. They're usually created through plate tectonics in subduction zones, but they can form anywhere magma is capable of breaking through to the surface.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Locating volcanoes ==&lt;br /&gt;
[[Image:Volcanoes-located.gif|thumb|400px|right|In order to begin on the volcano the starting plot must cover the ≈. Also note the volcano's name displayed under the biome information - this will be shown even if your plot isn't over the caldera. Click on this image to see the larger version.]]&lt;br /&gt;
&lt;br /&gt;
In Dwarf Fortress, volcanoes are named [[mountain]]s that additionally provide a source of [[magma]].&lt;br /&gt;
&lt;br /&gt;
Volcanoes tend to occur around the rim of [[ocean]]s. Sometimes, probably in a nod to shield volcanoes which form from heavy molten rocks, volcanoes also form in the middle of oceans. In other locations their placement appears to be random; they are not always associated with [[mountain]] ranges or other rocky terrain. They do not appear on the World Map window and must be found through the Region Map.&lt;br /&gt;
&lt;br /&gt;
To start on a map that includes a volcano, you will have to search for one. On the fortress location selection screen, they are not visible on the world map. Scroll around the world looking for a red ^ in the regional map. Select that space, and in the local map, move your starting area to include the square with a dark red ≈, which is the caldera.  There may also be additional local magma vents in nearby tiles around the volcano.&lt;br /&gt;
&lt;br /&gt;
Very rarely a [[magma vent]] will exist in an area with no volcanoes nearby.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Living on a volcano ==&lt;br /&gt;
&lt;br /&gt;
Volcanoes provide ready access to [[obsidian]], which a [[craftsdwarf]] can form into a rock short sword. It can also be used to make more valuable rock crafts and furniture. It's possible to divert water into magma to form your own obsidian, although it's often present in great quantities.&lt;br /&gt;
&lt;br /&gt;
The volcanic activity also leads to an abundance of heavy extrusive igneous rock (such as basalt, felsite and andesite) under a layer of farmable materials. The nature of these rock layers also provides for many useful ores such as [[iron]] (through hematite or other means), [[gold]], [[galena]], and other non-precious metals. The rock also provides useful gems such as [[turquoise]]s and [[zircon]]s, and occasionally [[diamond]]s. Genuine volcanoes sometimes have other interesting features, similar to named mountains: they are frequently sites for [[cave]]s, often have a wider than usual variety of [[stone]] and [[ore]], and may include unusual features such as [[cave river]]s, [[chasm]]s or [[pit]]s.&lt;br /&gt;
&lt;br /&gt;
Occasionally your group may end up embarking over lava, and it may be time to reembark. Other times a message about the cavern collapsing may occur, and this may be due to a pool of water which was spawned above the volcano's crater, instantly crystalizing the magma and then falling into the crater.&lt;br /&gt;

&lt;div&gt;An '''ocean''' is an immense volume of saltwater.&lt;br /&gt;
&lt;br /&gt;
== Oceans in Dwarf Fortress ==&lt;br /&gt;
Oceans are inhospitable areas for dwarves, and it is impossible to found a fort solely in an oceanic [[biome]]. There are generally a couple oceans on every generated map, they come in three varieties, based on temperature, which have little effect on their workings: Arctic, Temperate and Tropical.&lt;br /&gt;
&lt;br /&gt;
They tend to have a heavy effect on the surrounding geography of the generated world. [[Volcano]]es can often be found around the perimeter of the ocean, and this tends to be easiest place to find them. [[Marsh]]es and [[swamp]]s also tend to form around oceanic coastlines, especially near rivers. The land surrounding oceans also tends to have a high water table, resulting in [[aquifer]]s close to the surface.&lt;br /&gt;
&lt;br /&gt;
Sometimes you may find [[Driftwood|driftwood]].&lt;br /&gt;
&lt;br /&gt;
== Living by an Ocean ==&lt;br /&gt;
Despite the multitude of warnings that the fortress selection screen displays, ocean squares can be quite habitable - provided they are chosen well.&lt;br /&gt;
&lt;br /&gt;
[[Image:Ocean-unique-features.GIF|thumb|400px|right| An oceanic shoreline. A wave crashes into the beach causing mist; on the right an exposed vein of Native Platinum is visible through the erosion during world generation. Stacks of driftwood also cover the beaches.]]&lt;br /&gt;
&lt;br /&gt;
Oceans have a multitude of benefits: they're generally sparsely populated, they usually have an abundance of arable soil, and the nearby aquifer will provide an accessible source of water. Oceans also provide a few unique geographic features, including stacks of driftwood and ocean waves - which crash against the beach to produce mist. The erosion caused by waves also tends to leave numerous exposed mineral veins and [[gem]] deposits at sealevel, if you're lucky. There also tend to be a lot of sea creatures and fish, although their fishability lies in doubt (also, oceans of haunted-type surroundings may be prone to more vicious creatures that aren't confined to the briney deep).&lt;br /&gt;
&lt;br /&gt;
Despite that, oceanic shorlines can be difficult starting areas. It is important to check for some variation in topography when choosing an ocean location, as the ground is almost always water-laden one tile down from sea-level. Even if slightly hilly terrain is found, there is no guarantee that stone will still be accessible. Forests tend to make good biome additions, as they tend to have more varied terrain than marshes and swamps. When also picking a forest it is important that the treeline extends at least two tiles away from the shoreline on the Local Map, otherwise you may potentially only have stacks of driftwood and no actual trees and shrubs.&lt;br /&gt;
&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;A mountain is a naturally high elevation usually culminating in a peak. They are usually formed by the collision of tectonic plates or through volcanic activity.  [[Volcano]]es are mountains, but mountains are not necessarily volcanoes.&lt;br /&gt;
&lt;br /&gt;
As part of a starting site, mountains provide jagged terrain and impassable cliffs. They usually have very limited [[water]] resources, i.e., few ponds or streams, although many streams and rivers originate from the base of mountain ranges.  They often have sparse vegetation, and depending on the elevation may lack any sort of usable [[soil]].&lt;br /&gt;
&lt;br /&gt;
The stratification listed for mountains in Dwarf Fortress usually consists of one lighter rock type, generally a sedimentary stone (such as limestone, mudstone or dolomite), and then two further layers of heavy intrusive igneous (such as Granite, Rhyolite, or Gabbro) or metamorphic rock (such as Gneiss, Quartzite, or Phyllite). Stone, and subsequently ores, are always in abundance in mountain [[biome]]s.&lt;br /&gt;
&lt;br /&gt;
It is not possible to start a fortress on an exclusively mountain biome; however, fortress sites can straddle mountains on one side and more (or less) hospitable biome on the other, which will provide more valuable diversity of wildlife and resources.&lt;br /&gt;
&lt;br /&gt;
Mountains imply high elevation in the surrounding area.  This can result in a &amp;quot;forest&amp;quot; biome that does not actually have any trees, since above a certain elevation there may be no [[soil]] and therefore no place for trees to actually grow.  When choosing a starting fortress site, be sure to check the elevation map (using the tab key), and try to get a mix of low and medium or high elevations if possible.&lt;br /&gt;
&lt;br /&gt;
Unique features such as [[chasm]]s, [[cave river]]s and [[glowing pit|pit]]s are exclusive to mountains.&lt;br /&gt;

&lt;div&gt;Cave lakes can be found buried in mountains. They are about the size of a magma chamber but only two or three levels deep.&lt;br /&gt;
&lt;br /&gt;
They offer a fine habitat for various dangerous creatures&lt;br /&gt;
These include&lt;br /&gt;
&lt;br /&gt;
*Olman&lt;br /&gt;
*Cave Crocadile &lt;br /&gt;
*Frogman&lt;br /&gt;
&lt;br /&gt;
It is not known yet whether you can have an [[underground forest]] operation with a cave lake, as you can with a [[cave river]].&lt;br /&gt;

&lt;div&gt;Chasms appear similarly to rivers, but are not visible on the Local/Region/World maps.  They are similar to the DFv0.23 chasms except that they are not guaranteed, seem to use the same river-generation code for the fortress map (a &amp;quot;chasm tributary&amp;quot; has been observed), and occupy all depths.&lt;br /&gt;
&lt;br /&gt;
Chasms are much more common on named [[mountain]]s and [[volcano]]es, along with other special features such as [[cave river]]s.&lt;br /&gt;
&lt;br /&gt;
Chasms are possibly the only feature that can create Extreme Cliffs (20+) that may be observed on the Local Map.&lt;br /&gt;
&lt;br /&gt;
Chasms can also appear in a rounded shape, as below:&lt;br /&gt;
&lt;br /&gt;
[[Image:chasm.PNG]]&lt;br /&gt;
&lt;br /&gt;
== Uses ==&lt;br /&gt;
&lt;br /&gt;
A technique of building a platform over the chasm, and then severing the platform from the wall, can permanently dispose of garbage or excess stone set on top.&lt;br /&gt;
&lt;br /&gt;
It may still be possible to chasm refuse as it was in earlier versions. Try designating a garbage dump [[activity zone]] over the chasm. Monsters may also spring from the chasm, and were provoked by the chasming of refuse in previous versions. It is unknown if these events still occur.&lt;br /&gt;
&lt;br /&gt;
== Hazards ==&lt;br /&gt;
&lt;br /&gt;
Dwarves fighting near the edges of cliffs have a propensity to dodge right off the precipice, falling to their deaths.&lt;br /&gt;
&lt;br /&gt;
The chasm is also home to many types of hostile creatures, including [[iron men]], [[giant cave swallow]]s, [[antmen]], [[giant cave spider]]s, and [[ratmen]].&lt;br /&gt;

&lt;div&gt;A cave is a natural formation that occurs in mountainous or rocky areas. Some caves may contain hostile creatures or [[water]], and vary in size from a few tiles to long, winding passageways.&lt;br /&gt;
&lt;br /&gt;
Caves tend to be somewhat rare when placing a fortress, and the easiest places to find them seem to be named locales such as [[mountain|mountains]] and [[volcano|volcanoes]].&lt;br /&gt;
&lt;br /&gt;
It is believed that the Dwarves' ancestors once lived in caves thousands of years ago, but most modern Dwarves scoff at the idea that their distant relatives could have lived in such base conditions.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;An aquifer is a subterranean layer of water-bearing rock or soil.  Attempts to mine through them will result in the mined-out squares immediately filling with water, effectively halting excavation at or below their level.  This, in conjunction with the fact that they are often located in areas rich in clay, loam, and sand, makes it difficult to find great quantities of stone in areas with aquifers, making for more challenging gameplay.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Dealing with Aquifers ==&lt;br /&gt;
&lt;br /&gt;
The challenges presented by an aquifer may be circumvented in several ways.  Firstly, much more of your equipment will likely be made from wood, especially early on, so it may help to be in a heavily forested area.  Once you've established your fortress a bit, you will also be able to trade for stone and metals if you run short.&lt;br /&gt;
&lt;br /&gt;
It is also worth noting that it sometimes possible to find some amount of stone above the aquifer.  It may help to create exploratory shafts searching for pockets of stone.  Be aware that mining along the level immediately above the aquifer will result in patches of 'damp stone,' which will flood if mined out;  these squares will flash with water when designating mining areas.&lt;br /&gt;
&lt;br /&gt;
===The Ore method===&lt;br /&gt;
On maps where the aquifer is not held in a layer of soil, but instead is held in a [[sedimentary layer]] such as [[sandstone]], it may be possible to tunnel down through deposits of [[ore]] such as [[magnetite]].  For this to work you have to find a spot where there is coincidentally an ore deposit on each Z-level you need to dig through.  This is only possible through tiresome trial and error, or through  the use of a [[Utilities|utility]] like reveal.exe.&lt;br /&gt;
&lt;br /&gt;
===The Magma method===&lt;br /&gt;
If you have access to a supply of magma, you can create your own obsidian caissons.  The water from the aquifer is not pressurized and magma is chunky, so it is safe to dig channels in aquifer.  Though you will have to re-dig a lot of channels due to an element of chance, you can create a pool of magma on the aquifer z-level, and then pinch the pool off from the supply of magma with water.  When it cools (which you can hasten with more water) you can dig down through the middle of a 3x3 patch of obsidian without flooding.  With larger starting patches, you can dig through multiple levels of aquifer.&lt;br /&gt;
&lt;br /&gt;
===The Pump Method===&lt;br /&gt;
It is possible to pump the water out of an aquifer; though the supply is apparently unlimited it can be pumped out faster than the water seeps in, allowing for a fairly safe area on the z level. This method is somewhat dangerous since problems with your pumps can lead to drowning, however, it allows a larger area to be cleared than most methods and can be done anywhere.  It's also easier to plan around a series of pumps than hoping you'll hit rock on the way down.&lt;br /&gt;
There is an example of how to get through an aquifer with pumps here:  http://mkv25.net/dfma/movie-120-aquifercmv&lt;br /&gt;
&lt;br /&gt;
===The Ice Method===&lt;br /&gt;
There is a simple method of getting past an aquifer although it is restricted to a small shaft down, and not possible on all maps.&lt;br /&gt;
You will need:&lt;br /&gt;
*9 pieces of material suitable for crafting [[Wall|Walls]] and floors.&lt;br /&gt;
*1 [[Carpenter]] or [[Mason]] (depending on your wall's building material of choice)&lt;br /&gt;
*1 [[Miner]] (using multiple miners runs the danger of one miner digging a channel on the floor another is standing on!)&lt;br /&gt;
*A map which freezes&lt;br /&gt;
&lt;br /&gt;
steps:&lt;br /&gt;
#Dig channels in a 5x5 square.&lt;br /&gt;
#Dig stairs on the outside of the square to allow access to the next level.&lt;br /&gt;
#Carefully dig channels underneath all the other channels and build another stair down.&lt;br /&gt;
#Continue down in this way until you're right above the water table.&lt;br /&gt;
#Dig channels around a central square.&lt;br /&gt;
#Wait for the water to freeze.&lt;br /&gt;
#The outer-most blocks of ice on the aquifer level will prevent the inner block from being damp.&lt;br /&gt;
#Dig a central set of stairs which will allow you to go through the aquifer level and access the levels below.&lt;br /&gt;
#If the map will warm up, make sure to surround the stairwell on the aquifer level with walls.&lt;br /&gt;
#This system can be expanded to allow for a bigger stairwell.&lt;br /&gt;
&lt;br /&gt;
diagram:&lt;br /&gt;
*&amp;lt;tt&amp;gt;C&amp;lt;/tt&amp;gt; - channel&lt;br /&gt;
*&amp;lt;tt&amp;gt;G&amp;lt;/tt&amp;gt; - grate&lt;br /&gt;
*&amp;lt;tt&amp;gt;W&amp;lt;/tt&amp;gt; - wall&lt;br /&gt;
*&amp;lt;tt&amp;gt;X&amp;lt;/tt&amp;gt; - up/down stairs&lt;br /&gt;
*&amp;lt;tt&amp;gt;&amp;gt;&amp;lt;/tt&amp;gt; - down stair&lt;br /&gt;
*&amp;lt;tt&amp;gt;&amp;lt;&amp;lt;/tt&amp;gt; - up stair&lt;br /&gt;
*&amp;lt;tt&amp;gt;I&amp;lt;/tt&amp;gt; - Ice/water&lt;br /&gt;

IWWWI&lt;br /&gt;
IIIII&lt;br /&gt;
&amp;lt;/pre&amp;gt;&lt;br /&gt;
&lt;br /&gt;
===Differing biomes===&lt;br /&gt;
If your local area has more than one biome, you may be able to dig down in one biome to bridge under an aquifer in another.  This won't work if the aquifer is present in all biomes, of course, but it may be useful in the case of a surprise aquifer that was not marked on the region selection screen.&lt;br /&gt;
&lt;br /&gt;
== Advantages of Aquifers ==&lt;br /&gt;
&lt;br /&gt;
It's worth noting that the presence of an aquifer, while challenging, does offer some slight advantages.  Firstly, much of the area underground but above the aquifer will be sand, clay, or loam, all of which can be planted in without requiring any kind of irrigation or flooding, allowing farming to get under way quicker and with less stress.  Additionally, the presence of water 3-4 z-levels below ground anywhere on the map makes placing wells a simpler task, as well as ensuring easy access to subterranean water supplies.&lt;br /&gt;

&lt;div&gt;Forests are areas with large amounts of densely packed [[Tree|trees]].&lt;br /&gt;
There are several types of both [[Tropical]] and [[Temperate]] forests. Forests typically have large amounts of plants and tons of available wood.&lt;br /&gt;

&lt;hr /&gt;
&lt;div&gt;A '''volcano''' is a vent in the planet's crust through which lava and pyroclastic materials are expelled. They're usually created through plate tectonics in subduction zones, but they can form anywhere magma is capable of breaking through to the surface.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Locating volcanoes ==&lt;br /&gt;
[[Image:Volcanoes-located.gif|thumb|400px|right|In order to begin on the volcano the starting plot must cover the ≈. Also note the volcano's name displayed under the biome information - this will be shown even if your plot isn't over the caldera. Click on this image to see the larger version.]]&lt;br /&gt;
&lt;br /&gt;
In Dwarf Fortress, volcanoes are named [[mountain]]s that additionally provide a source of [[magma]].&lt;br /&gt;
&lt;br /&gt;
Volcanoes tend to occur around the rim of [[ocean]]s. Sometimes, probably in a nod to shield volcanoes which form from heavy molten rocks, volcanoes also form in the middle of oceans. In other locations their placement appears to be random; they are not always associated with [[mountain]] ranges or other rocky terrain. They do not appear on the World Map window and must be found through the Region Map.&lt;br /&gt;
&lt;br /&gt;
To start on a map that includes a volcano, you will have to search for one. On the fortress location selection screen, they are not visible on the world map. Scroll around the world looking for a red ^ in the regional map. Select that space, and in the local map, move your starting area to include the square with a dark red ≈, which is the caldera.  There may also be additional local magma vents in nearby tiles around the volcano.&lt;br /&gt;
&lt;br /&gt;
Very rarely a [[magma vent]] will exist in an area with no volcanoes nearby.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== Living on a volcano ==&lt;br /&gt;
&lt;br /&gt;
Volcanoes provide ready access to [[obsidian]], which a [[craftsdwarf]] can form into a rock short sword. It can also be used to make more valuable rock crafts and furniture. It's possible to divert water into magma to form your own obsidian, although it's often present in great quantities.&lt;br /&gt;
&lt;br /&gt;
The volcanic activity also leads to an abundance of heavy extrusive igneous rock (such as basalt, felsite and andesite) under a layer of farmable materials. The nature of these rock layers also provides for many useful ores such as [[iron]] (through hematite or other means), [[gold]], [[galena]], and other non-precious metals. The rock also provides useful gems such as [[turquoise]]s and [[zircon]]s, and occasionally [[diamond]]s. Genuine volcanoes sometimes have other interesting features, similar to named mountains: they are frequently sites for [[cave]]s, often have a wider than usual variety of [[stone]] and [[ore]], and may include unusual features such as [[cave river]]s, [[chasm]]s or [[pit]]s.&lt;br /&gt;
&lt;br /&gt;
Occasionally your group may end up embarking over lava, and it may be time to reembark. Other times a message about the cavern collapsing may occur, and this may be due to a pool of water which was spawned above the volcano's crater, instantly crystalizing the magma and then falling into the crater.&lt;br /&gt;
