2019 Map of Allison

About this map

Arboles and Allison anchor this landscape where the high desert meets the northern reaches of the Navajo Reservoir. This modern survey illustrates the complex water management system of the San Juan Basin, featuring irrigation infrastructure such as the Miller Ditch, Darlington Ditch, and the N Pine River Lateral. The terrain is defined by the Piedra River drainage, which flows southward through deep cuts like Payan Canyon and Black Horse Canyon before joining the reservoir. High points including Piedra Peak and Haystack Mtn overlook the southern Colorado border, while the winding Piedra Trail and Windsurf Beach Trl indicate the area's recreational use. The map also documents the transition from ranching and irrigation to modern energy development, noted by the presence of Gas Wells Rd and a network of rural county roads.
