Mining operations dominate the high-altitude landscape of the Mosquito Range in this early 1960s survey. The map details a heavy concentration of silver and lead extraction sites, particularly around Breece Hill and the northern gulches. Notable workings include the Ibex Mines, Printer Boy Mine, and the Continental Chief Mine, reflecting the intensive industrial footprint of the Leadville mining district. The terrain is defined by massive peaks such as Mount Sherman and Horseshoe Mountain, with the National Forest Boundary splitting the area between the San Isabel and Pike National Forests.
