2013 Map of Mellen Hill

About this map

Dinosaur National Monument occupies the northwestern corner of this landscape, where the high desert terrain of the Colorado plateau is carved by an intricate system of seasonal drainages. The map reveals a transition from protected federal lands in the north to industrial resource extraction in the south, most notably where the Rangely Oil Field extends across the lower portion of the sheet. The topographical detail highlights the prominence of Mellen Hill and the long expanse of Raven Ridge, while the network of dry washes including East Twin Wash, West Twin Wash, and Twin Wash define the local hydrology. This 2013 survey serves as a modern record of the intersection between conservation, energy production, and the natural drainage patterns of the Coal Oil Basin.
