1991 Map of Supply Canyon

About this map

The Uintah and Ouray Indian Reservation dominates the western half of this landscape, where the high-altitude terrain is carved by a series of deep drainages. Long, parallel formations including Mormon Ridge, Ouray Ridge, and Went Ridge create a distinct north-south grain across the territory. This 1991 provisional map captures a remote corner of the Uinta Basin, showing the intricate network of canyons like Fivemile Canyon and Supply Canyon that feed into the Willow Creek system. Evidence of historic transit is visible along the Wagon and Road, which follows the high ground above Spring Creek. The map provides a detailed view of the natural water sources and high points, such as Windy Point, which were critical for navigating this complex geography before modern infrastructure reached the deeper canyons.
