It was created in 2019 to protect important natural features - particularly the Siberian snow sheep, and also the cultural heritage of the reindeer-herding indigenous Evenki people.

[3] [4][5] The park protects a remote region of the upper watershed of the Zeya River, on the southern slopes of the Toko-Stanovik mountain range.

Terrain in the park is notable for glacial valleys and lakes at the higher elevations, Pleistocene (Ice Age) volcanic plateaus and extinct mini-volcanic cones, and lower forests representing taiga of the northern Amur and southern Siberian types.

[4] The higher elevations of the park are in the Trans-Baikal Bald Mountain tundra ecoregion, making it part of a linked chain of mountain tundra (permafrost, moss and lichen, and bare rock) micro-regions stretching from Lake Baikal (1,300 km to the west of the park) to the Sea of Okhotsk 400 km to the east.

The park is a resting place for the critically endangered Siberian crane on its north–south migration route.
