2024 Map of Henry Gulch

About this map

The Red Rock River meanders across this portion of Beaverhead County, defining the drainage patterns of a landscape marked by deep gulches and tributary streams. Running south of the river, Henry Gulch and Centennial Gulch carve into the rising terrain, providing a stark contrast to the broader valley floor. Modern access to this corner of Montana is primarily facilitated by Lima Dam Rd, which skirts the river's path and connects the sparse high-country drainages. To the north, the terrain is segmented by Basin Creek and Little Basin Creek, reflecting a characteristic Western watershed where seasonal water flow dictates the shape of the land. This survey from the U.S. Geological Survey details the township and range boundaries that still organize this area, illustrating how surveying lines intersect with natural features like the winding river and its neighboring canyons.
