The Dolores River cuts through the northwest corner of this San Miguel County landscape, defining a region of dramatic topographic shifts and deep drainages. The area is anchored by the broad Big Gypsum Valley and the neighboring Disappointment Valley, where seasonal watercourses like Big Gypsum Cr and Disappointment Cr have carved out a complex system of canyons and draws. Notable landforms such as Cape Horn and the eponymous Hamm Canyon dominate the elevation contours, illustrating the erosional history of the Colorado Plateau.
