1958 Map of Monarch Lake

About this map

Monarch Lake sits at the western edge of this 1958 survey, serving as a gateway to the high-altitude terrain of the Arapaho National Forest. The landscape is dominated by the Continental Divide, which separates the headwaters of Arapaho Creek and Buchanan Creek from the eastern slopes of the Roosevelt National Forest. This era of mapping documents the glacial features of the Front Range, including the Arapaho Glacier and Peck Glacier, alongside a network of established wilderness routes such as the Arapaho Pass Trail and Buchanan Pass Trail. Evidence of earlier resource extraction persists at the High Lonesome Mine near Lonesome Peak, while the names of prominent summits like Mount Achonee and Lone Eagle Peak reflect the climbing history of the Indian Peaks. The map illustrates the transition from the relatively level Strawberry Bench and Caribou Meadow to the high basins and cirques of Wheeler Basin.
