2011 Map of Dunckley Pass

About this map

Dunckley Pass serves as a critical high-altitude crossing in this portion of the Flat Tops wilderness, anchoring a landscape defined by hydraulic engineering and alpine drainage. The 2011 survey highlights an intricate network of water management features, including Sheriff Reservoir and Haley Reservoir, both supported by their respective Sheriff Dam and Haley Dam. These reservoirs, along with smaller bodies like J O K Reservoir and Gill Reservoir, suggest a history of high-country ranching and water diversion, further evidenced by the Egry Mesa Ditch skirting the edge of Egry Mesa. The area is bisected by the East Fork Williams Fork and Trout Creek, while prominent terrain features such as Baldy Mountain and Dunckley Flat define the local topography. This map is essential for tracing the physical development of water rights and access routes through this part of the Colorado Rockies.
