1958 Map of Loveland Pass

About this map

The Continental Divide serves as the literal backbone of this high-altitude landscape, defining the jagged boundaries between Grand, Summit, and Clear Creek counties. This mid-century survey, with revisions from the 1970s, captures a critical era of civil engineering in the Rockies, most notably the subterranean path of the Eisenhower Memorial Tunnel. While the tunnel bores beneath the mountains, the historic surface route over Loveland Pass remains a primary feature, winding through the Arapaho National Forest. The map documents a complex drainage network where the headwaters of the Middle Fork and South Fork Williams Fork begin their descent. High alpine peaks like Pettingell Peak and Hagar Mountain overlook the deep incisions of Herman Gulch and Dry Gulch, while small bodies of water such as Pass Lake and Herman Lake sit perched within the steep glacial terrain.
