About this map

Helena National Forest land dominates the eastern half of this terrain, where the slopes of Marcum Mountain and Trapper Mountain rise above the river valley. The landscape is defined by the winding course of the Blackfoot River, which transitions from the steep forest edge into the open expanses of Kleinschmidt Flat. This 2001 revision illustrates a complex water management system for ranching and agriculture, featuring the Helmville Canal, North Canal, and Lincoln Slough.

Evidence of local industry and recreation is scattered throughout the Powell County backcountry, from the Mineral Hill Fishing Access to various Prospects and Gravel Pits. Significant ranching outposts like Steeles Ranch and the settlement at Coughlin provide touchpoints for genealogists tracking family history in the Montana wilderness. The presence of a Gaging Station on the river and numerous named tributaries like Wasson Creek and Nevada Creek underscores the region's reliance on its mountain-fed waterways.
