1970 Map of Willow Lakes

About this map

The high peaks of the Gore Range dominate this 1970 study of the boundary between Eagle and Summit Counties. This alpine landscape is defined by its dramatic glacial basins and high-altitude lakes, including the namesake Willow Lakes, Slate Lake, and Boulder Lake. The survey captures a wilderness interface where the Arapaho National Forest meets the White River National Forest, reflecting a period when recreation and resource extraction overlapped in these mountains. Evidence of the area's mining history is preserved through labels for the Boss Mine and various Prospects scattered across the ridges. Along the Blue River, the presence of a Gaging Station and established campsites like Blue River Campground and Boulder Creek Campground indicates the early development of modern water management and backcountry access. This map provides a clear record of the primitive Pack Trails and drainage systems that shaped human movement through these high-elevation passes long before extensive modern infrastructure.
