Many Glacier is mostly the eastern border of Glacier pack territory. It is also the reasoning for the pack's name. A few of the glaciers reach deeper into Glacier territory than just the border, which is what forms the main portion of Many Glacier within the territory. These glaciers are giant ice formations that look a lot like mountains (they form a mini mountain range). The glaciers move slowly over time. In the wolves' time here in Everfrost they have not moved much, but they have moved. Maybe it has been only a few feet, maybe several yards, but they have moved, and they will continue to move until the end of time.

Avalanche River cuts off the westernmost portion of Glacier territory. It is a swift-flowing river that slows during the winter, when some of it freezes over. During the summer, however, it is especially dangerous because it is fed by the runoffs of melted snow from the mountains and glaciers throughout Everfrost. Around some parts of the river is marshland where moose can be found, though they are rarer during the winter. They river is a source of life for the animals of Glacier territory, as there are few lakes and large rivers in the area (though there are plenty of lakes and streams). Avalanche River is what keeps Glacier pack and territory alive.
