About this map

Roberts Mtn and Rogers Mtn anchor this high-elevation landscape in Lewis and Clark County, where the topography is defined by dramatic escarpments and deep drainages. The northern portion of the map is dominated by prominent geological formations known as The Reef and Rattlesnake Reef, which overlook a network of creek-fed gulches. These natural corridors, including Denton Gulch and Lannigan Gulch, have historically dictated the placement of back-country access roads like Allen Gulch Rd and Woods Creek Rd.

Hydrography in this area is characterized by seasonal and perennial flows that carve through the mountain passes, such as Wells Fork Rock Cr and French Cr. The map reveals a land primarily utilized for its natural resources and wilderness navigation, evidenced by the presence of Hicks Trl and the Rock Creek Loop. Settlement is sparse, with the terrain instead marked by named peaks like Toms Peak and Butcher Mtn, reflecting a region dedicated to forestry, grazing, or watershed management rather than urban development.
