The massif of the Black Hills (Yavapai County) form the east border of Lonesome Valley.

The Granite Mountain (Arizona) region at the west-southwest, has a large dissected alluvial section at its northeast.

From the southwest its route comes from Presott, passes Watson Lake, and then exits the Granite Dells to traverse to Chino Valley, Arizona.

The small canyon below the reservoir is at the west end of Little Black Mesa, and the outfall site of Granite Creek with the Verde River.
