1958 Map of Monarch Lake

About this map

The Continental Divide forms a dramatic eastern boundary for this high-altitude landscape, where the Arapaho National Forest and Roosevelt National Forest meet. The terrain is defined by its glacial heritage, featuring the prominent Arapaho Glacier tucked beneath North Arapaho Peak and South Arapaho Peak. This 1958 survey captures a remote wilderness accessible primarily through a network of established footpaths, such as the Buchanan Pass Trail and the High Lonesome Trail. In the lower elevations, Monarch Lake sits as a primary landmark, while higher basins are dotted with alpine waters like Crater Lake and Lake Dorothy. The map documents early recreation and extraction sites, including the High Lonesome Mine and several remote campsites like Shelter Rock Campground. This area demonstrates the classic transition from timbered valleys along Meadow Creek to the jagged ridgelines of Niwot Ridge and Mount Achonee.
