About this map

Ridgway and the nearby settlement of Dallas anchor this 2019 survey of the San Juan Mountains' northern foothills. The landscape is defined by the high elevations of Log Hill Mesa and Enchanted Mesa, which overlook the expansive waters of the Ridgway Reservoir. Along the Uncompahgre River, the Uncompahgre Riverway Trail follows the valley floor, passing the notable Orvis Hot Spring south of the main town site.

A complex network of water management features, including Alkali Ditch Number 1 and Sheva Ditch, illustrates the engineering required to support this arid high-country environment. The eastern portion of the map climbs into the Uncompahgre National Forest, where steep drainage systems like Cow Creek and Owl Creek carve through Onion Hill and Ramshorn Ridge. This modern topographic study captures the intersection of recreational development and the traditional ranching infrastructure that has shaped Ouray County for generations.
