2022 Map of Allison

About this map

Arboles and Allison anchor the southwestern corner of Archuleta County, where the high desert terrain of the Southern Ute reservation meets the expansive waters of the Navajo Reservoir. This modern U.S. Geological Survey representation details a landscape defined by sharp elevation shifts and water management, where the Piedra River carves through canyons like Black Horse Canyon and Payan Canyon before reaching the reservoir. The influence of agricultural history is evident in the network of irrigation channels, including the Miller Ditch and Darlington Ditch, which parallel the natural drainage of Sambrito Creek. Prominent landmarks such as Piedra Peak and Haystack Mtn provide vertical relief against the winding road network of Co RD 973 and Trujillo Rd. Recreational development is noted near the shoreline with the Watchable Wildlife Overlook Trl and Deer Park, illustrating the region's contemporary character as both a working landscape and a public refuge.
