Lewis & Clark National Forest encompasses the high-altitude terrain where Cascade and Meagher counties meet in this 2020 survey. The landscape is defined by the sharp divide of Deep Creek Ridge and Monument Ridge, which separate the drainage of the N Fork Deep Cr from the lower Blankenbaker Flats. This area serves as a significant hydrological headwaters region, with numerous waterways including Logging Cr and Sand Coulee Cr carving out deep features like Devil Canyon and Wild Rock Canyon.
