The Northern Rocky Mountains Park provides representation of the Eastern Muskwa Ranges, Muskwa Foothills and Muskwa Plateau ecosections. The park landscape consists of a series of northwest-southeast trending valley and ridges. Glaciation has resulted in broad U-shaped river valley bottoms, mountain cirques and morainal ridges.
The mountains in the Muskwa Range have steep eastern faces with gentler grades on western aspects. Peak summit elevations range from Mount Mary Henry at 2641 m to Mount Sylvia at 2942 m. In comparison to the southern Rocky Mountains, the Muskwa Ranges are older and generally show evidence of more complex tectonic deformation that results in spectacular geological features.
One of the notable features of the Northern Rocky Mountains Park is the diversity of water features. The area is accentuated by major rivers, clear, cold streams, waterfalls, rapids, small glaciers and lakes. The rivers include the Tetsa, Chischa, Tuchodi and Muskwa and the main creeks are the Gathto, Kluachesi, Dead Dog and Chlotapecta. All creeks and rivers in the Northern Rocky Mountains flow into the Muskwa. Kluachesi and Tetsa are examples of the larger lakes in the area, but the largest and most important water recreation feature in the Northern Rocky Mountains Park is the upper and lower Tuchodi Lakes.
The boreal white and black spruce, spruce willow birch and the alpine tundra biogeoclimatic zones are found in the Northern Rocky Mountains Park. Forests in the valley bottoms are dominated by white spruce and aspen, and are replaced by sub-alpine fir and white spruce at higher elevations.
Alpine plant communities consist of dwarf willows, grasses, sedges, forbs and lichens. The park also has numerous wetlands and native grasslands. Old growth white spruce forests can be found along the major river valley bottoms.
A diverse variety of wildlife inhabits this northeastern mountain landscape. The area provides high quality habitat for moose, elk, stone sheep and mountain goat. The abundance of prey supports predator species such as wolves and grizzly and black bears.
Other important wildlife includes furbearers such as marten, fisher, weasels and wolverines. Information on small mammals, amphibians, birds, invertebrates and reptiles is relatively unknown. Lake trout, rainbow trout, bull trout, arctic grayling and lake whitefish are some of the important sport fish species in the Northern Rocky Mountains Park.
