The river drains approximately of boreal forest and muskeg. Other names for bogs include mire, quagmire, and muskeg; alkaline mires are called fens. The typical habitat is on moorlands, tundra, muskeg and spruce forests. Bogs, fens, and marshes together comprise "muskeg" regions. The overburden consists of water-laden muskeg (peat bog) over top of clay and barren sand. In areas of muskeg, tussocks form and may collect algae. The surrounding landscape consists of primarily taiga forest with sand hills and muskeg. In areas of muskeg there are stands of black spruce or tamarack. It is surrounded to the north and west by muskeg tundra. They lie under of waterlogged muskeg, of clay and barren sand. Much of the land is rock, ice, muskeg, or less productive forest on steep slopes. Large tracts of this soil existing in Siberia may be called muskeg or bogland interchangeably. Two belt tracks were common on early model Bombardiers and muskeg machines. Because of the water beneath, the muskeg surface sometimes ripples underfoot. They produced it under the name Muskeg tractor.
