Wetterhorn Peak and the surrounding high-altitude terrain of the Uncompahgre National Forest define this 1963 survey, later updated to reflect the establishment of the Big Blue Wilderness. The landscape is a network of sharp ridges and deep drainage basins, where headwaters like the West Fork Cimarron River and Middle Fork Cimarron River begin their descent. Small-scale mining activity is evident through scattered labels for a Mine and various prospects near Mary Alice Creek and Porphyry Basin, suggesting the era's continued interest in the mineral potential of these remote slopes.
