Also, because of a glacier's isolation (generally), it is entirely possible that you won't see a caravan from the Mountainhomes for anywhere up to 3 years. Migrants may be even more rare. On the plus side, though, no hostile nations should bother you for a while. | Also, because of a glacier's isolation (generally), it is entirely possible that you won't see a caravan from the Mountainhomes for anywhere up to 3 years.

Trading is '''essential'''. An easy source of income is rock crafts. All that rock you cut out making wells and farms you can sell to merchants who visit. Begin as soon as you can because you need to import a lot of wood if you plan on having beds or fuel for making metal objects. | Trading is '''essential'''. An easy source of income is rock crafts.

− | + | {{L|Ice}} is everywhere, so read up on it before you make any major plans. One difference between regular ice and glacier ice that you may want to know before you head out is that, unlike ice from other biomes, glacier ice constructions and workshops do not melt when above ground in the "summer". The disadvantage, however, is that it is more difficult to use the ice as a potential water source. Note that mined out chunks of ice, when melted by being brought underground, will '''not''' produce usable water. {{Bug|360}} | |

Also, water is needed at {{L|hospital}}s for cleaning and to give the wounded something to drink. There are two ways to get water on a glacier. |

Further, if the pool abuts the edge of your embark area, new water will fill in from the edge, giving you an infinite source of water. On the down side, it can take a while to find the caverns, since digging straight down isn't guaranteed to breach them, and there's a small chance of aquatic monster escaping from the cavern. |
To safely (without having to wander around inside the cavern) tap into an underground pool, consider the following diagram: | To safely (without having to wander around inside the cavern) tap into an underground pool, consider the following diagram: | ||

To begin, it is best to clear out a large section of the rock underneath all the ice. Then cut out a 6x6 section of ice (it is easiest to cut out two squares around the part you want to drop so that you won't have any fatalities while channeling out the section of ice). Channel out the entire piece of ice and it will fall into that cleared out section, immediately defrosting and flooding the area. Now you can farm! | To begin, it is best to clear out a large section of the rock underneath all the ice.

Ice that is underground melts, but creates only useless puddles of water (marked as a cyan double tilde) identical to water dumped from a bucket. These puddles can only be cleaned. They cannot form usable water (blue tilde with depth attribute). Dumping block after block of mined ice blocks indoors will simply result in a huge stack of useless "water". | Ice that is underground melts, but creates only useless puddles of water (marked as a cyan double tilde) identical to water dumped from a bucket.
