Ridgway and the historic settlement of Dallas sit along the Uncompahgre River, where the high desert mesa meets the rising slopes of the Uncompahgre National Forest. This modern record of the valley reveals a landscape defined by water management and recreational development. An extensive network of irrigation features, including Alkali Ditch Number 1 and Alkali Ditch Number 2, supports the agricultural bottomlands near Dry Gulch, while the surrounding hills are crisscrossed by a dense modern trail system with names like Rattlesnake Trl and Marni Mata Trl. The presence of the Orvis Hot Spring south of town underscores the geothermal character of the region. To the east, the terrain climbs toward Onion Hill and Ramshorn Ridge, marking the transition into the deeper canyons and drainages of Courthouse Cr and Flume Cr.
