About this map

The Stemple Pass summit within the Helena National Forest serves as a critical waypoint for travelers navigating the crest of the Lewis and Clark Range. This modern survey reveals the high-altitude hydrology of the continental divide, where numerous seasonal and perennial headwaters such as Black Diamond Cr, Hogum Creek, and Rooster Bill Cr begin their descent toward the Blackfoot River or the Missouri basin.

Evidence of historical land use and water management is visible through features like the Pilgeram Ditch and the network of gulches, including Whiskey Gulch and Page Gulch, which speak to the region's legacy of prospecting and resource extraction. The winding route of the Continental Divide National Scenic Trail traverses the center of the map, while Stemple Pass Rd and Gravelly Range Rd provide modern access through this high-country landscape.
