2010 Map of Mellen Hill

About this map

Mellen Hill rises as the central landmark in this high-desert landscape of Northwest Colorado, where complex drainage systems and isolated cattle-range infrastructure define the terrain. The northern half of the quadrangle is dominated by the convergence of West Twin Wash and East Twin Wash, which weave through a network of dry draws and seasonal drainages. Water management is evidenced by the Dripping Rock Reservoir situated along Dripping Rock Rd, serving as a critical point for local ranching or resource operations. In the southeastern portion, the named Coal Oil Gulch hints at the region's mineral history, while the elevated Raven Ridge provides a distinct topographic boundary to the southwest. This 2010 survey by the U.S. Geological Survey illustrates a sparsely populated but active corridor marked by county routes like County Rd 98 and County Hwy 1.
