Lolo National Forest and Helena National Forest converge in this high-altitude landscape of Lewis and Clark County, dominated by the drainage systems of the North Fork Blackfoot River and the Dry Fork N Fork Blackfoot River. The terrain is defined by prominent peaks and ridges, including the namesake Lake Mtn and Mineral Hill, while geological instability is noted at Big Slide. Surveyed in 2014, the map traces several creek systems such as Yakey Cr, McDermott Cr, and Madison Cr as they navigate the deep contours of the divide. The presence of Windy Pass and North Fork Falls suggests the remote, roadless character of this mountain wilderness, which remains primarily defined by its hydrological features and the administrative boundaries of the national forest system.
