2014 Map of Prairie Reef

About this map

Prairie Reef rises as a prominent landmark within the Lewis & Clark National Forest, anchoring a landscape defined by the drainage systems of the West Fork South Fork Sun River and Ahorn Cr. This 2014 survey captures the wilderness character of the Lewis and Clark Range, where high-elevation features like Red Butte and Junction Mtn overlook deep drainages such as Grizzly Gulch and No Name Gulch. The map meticulously tracks the headwaters of numerous creeks, including the Blind Fork and Lost Fork Ahorn Cr, which carve through the terrain along the border of Powell County and Lewis and Clark County. For those studying the geography of the northern Rockies, the sheet provides exact placement for remote points like Hermit Lake and specialized wildlife-named features such as Black Bear Cr and White Bear Cr.
