Taiyuan Ice Dungeon has two zones unofficially named by the hunters who entered. First was the Hunting Ground, which covered most of the snowy dungeon. This zone stretches from the dungeon's entrance, the vast snowy plains around it, to the pine forest and small ice hills.
It was called the Hunting Ground, not because of the fact this is the place where hunters hunt and slay dungeon monsters. Instead, this is the place where Yetis hunts for their food.
The sparse pine forest is the home of critters that make up the diet of these furry giants.
The second zone is the settlement of the Yetis. It is located in the north-central part of the dungeon and is characterized by the clump of snowy hills. These bumps are actually the home created by the Yetis.
They are a slightly unrefined and humongous version of an igloo.
