1945 Map of Mount Logan

About this map

The North Fork South Platte River carves a deep path through the Pike National Forest in this mid-1940s survey of the high Rockies. Settlements along this corridor, including Webster and Grant, follow the low ground beneath the massive peaks of Mount Logan and Mount Blaine. The inclusion of the Roberts Tunnel reflects the era's significant water engineering efforts by the Denver Board of Water Commissioners to divert mountain runoff toward the city. The landscape is defined by its drainages, where named gulches like Frenchman Gulch and Whiteside Gulch feed into Geneva Creek. To the south, the terrain rises sharply toward the North Twin Cone Peak and South Twin Cone Peak, marking the northern edge of the Kenosha Mtns. This map serves as a detailed record of the transport and water infrastructure that supported both local ranching and the growing needs of the Front Range.
