2011 Map of Knife Edge

About this map

Rio Grande waters dominate the northern reaches of this high-elevation Mineral County landscape, where the river flows between River Hill and the dramatic walls of Box Canyon. This 2011 survey details a complex system of alpine water management and drainage, with several reservoirs and their associated structures, including Wee Ruby Dam, Big Ruby Dam, and Trout Lake Dam, controlling the flow from the surrounding peaks. High-altitude terrain is defined by prominent landmarks like Chief Mountain and the sharp ridge of Knife Edge to the south. The area remains largely focused on recreation and resource management, centered around the River Hill Campground and the network of drainages such as Little Squaw Creek and Texas Creek that feed into the larger river system. Local access is primarily via Co RD 18 and forest road 520 2e, tracing the paths of ancient canyons like Sawmill Canyon and Road Canyon.
