1961 Map of Porter Mountain

USGS Topo · Published 1963

About this map

Grand Mesa National Forest and Gunnison National Forest meet at this high-altitude point in the Colorado backcountry, where Mesa and Delta counties converge. The 1961 landscape is defined by a sophisticated network of early water management systems, including the Silver Spruce Ditch, Bull Elk Ditch, and Carnahan Ditch, which redirect high-country runoff across the plateau. High peaks like Porter Mountain and Lenna Peak tower over sprawling open spaces such as Stillwater Park and Grass Park.
