The Glacier is a biome in the Digital World. It is the biome with the least spawning Digimon. The levels in this biome range from 60-80.
The surface of the Glacier Biome is comprised mostly of Digiice. Under the surface, however, there is a layer of Snow, Huanglong Ore and Digistone. The surface holds a lot of high mountains, like you would see in the Extreme Hills biome in the Overworld. Inbetween those mountains there are lakes that are mostly frozen over.
