1967 Map of Sand Creek Pass

About this map

Roosevelt National Forest defines the southern reach of this high-elevation landscape, where the state boundary between Wyoming and Colorado cuts across rugged drainages and granite formations. Published by the Geological Survey following field checks in 1967, the map documents a terrain primarily shaped by seasonal waterways and local landmarks like Chimney Rock and the massive elevation of Bull Mountain. The hydrology is particularly well-detailed, featuring various sources such as Jimmy Spring, Jimmy Creek Spring, and a lone Spring near Bull Run Creek. Movement through this high country is limited to a network of established paths, including a Jeep Trail and Pack Trail, reflecting the area's use for ranching or forestry rather than permanent settlement. To the east, the rising land of Boulder Ridge separates the complex creek systems, while Sand Creek Pass serves as a critical natural transit point.
