1958 Map of Monarch Lake

USGS Topo · Published 1978

About this map

Monarch Lake sits at the western edge of this 1958 survey, serving as a catchment for the drainage of Buchanan Creek and Cascade Creek. The terrain is dominated by the high-altitude wall of the Continental Divide, which separates the Arapaho National Forest in Grand County from the Roosevelt National Forest in Boulder County. Evidence of early 20th-century prospecting remains at the High Lonesome Mine and the Fourth of July Mine, reflecting the era's mining activity in these difficult elevations. The map details a network of high-country routes including the Buchanan Pass Trail and High Lonesome Trail, which navigate between jagged summits like Lone Eagle Peak and glacial features such as the Arapaho Glacier. The presence of several glaciers, including Peck Glacier and Fair Glacier, highlights the alpine environment of the Indian Peaks range during this mid-century period.
