Continental Reservoir and the headwaters of the Rio Grande drainage define this high-elevation landscape in Mineral County. The area is characterized by an extensive network of water management infrastructure, including the S Lazy U Reservoirs, Regan Lake, and Troutvale Reservoir Number 1. These alpine water bodies, many held by structures like Hermit Number 1 Dam and Road Canyon Number 1 Dam, illustrate the 20th-century focus on irrigation and water storage in the Colorado mountains.
