About this map

The Continental Divide bisects this high-elevation region where the Arapaho National Forest meets the Roosevelt National Forest. This survey centers on the engineering marvel of the Moffat railroad line, tracing its path from the town of Winter Park to the East Portal of the Moffat Tunnel. The map illustrates the dramatic transition from the rail tunnel deep beneath the mountains to the high-alpine crossings of the old Moffat Road, which winds past landmarks like Riflesight Notch and the Riflesight Trestle.

Historically significant routes like the Boulder Wagon road and the Continental Divide National Scenic Trail converge near Rollins Pass, surrounded by a dense concentration of alpine lakes such as Yankee Doodle Lake and Jasper Lake. The proximity of these features shows the evolution of transit across the divide, from early wagon paths and the exposed high-altitude rails to the modern subterranean tunnel system.
