1958 Map of Jefferson

About this map

The Continental Divide forms a natural spine along the high peaks of this 1950s survey, marking the boundary between Summit Co and Park Co. High-altitude landmarks like Whale Peak and Jefferson Lake dominate the northwestern terrain, where water drains through narrow corridors such as Handcart Gulch and Gibson Gulch toward the South Platte River. The landscape shifts from the high timber of Pike National Forest and Arapahoe National Forest to the open ranching country at the northern edge of South Park.
