The only forest, located in the North of this Terra. Very green, though almost unnatural for this area. the thick, permanent ice under the dirt is thinner here, giving for room for growth. This is the best place, besides your warm dens, to have some safety. Some large boulders build a large shelter of the snow, if it does get through the tree's, wich is pretty doubtful.
The Vein River has some soft dirt made area's, very useful for making any dens. Remember, you may not enter a den unless the owners of the den allow it. It is normally that you're invited, instead of asking, permission is less rude. Pups must stay in the den for a whole season before they are allowed out into the open.
