About this map

Manti-La Sal National Forest dominates this high-altitude landscape in San Juan County, where sheer cliffs and deep drainages define the geography. The map reveals a network of livestock grazing lands, including Redd Pasture and Poso Pasture, interspersed with dramatic geological features like Steamboat Point and Queens Arch. These named landmarks, alongside the prominent Horse Mountain, reflect a history of cattle ranching and early exploration across the Colorado Plateau.

Remote transport routes like Sweet Alice Rd and the White Rim Trail W provide access to this isolated terrain, connecting it to the broader canyonlands region. Significant drainages such as Poison Canyon, Ruin Canyon, and Dark Canyon carved deep into the plateau, create a complex topography of mesas and points, including the notable Deadman Point. Water sources are few, with Duck Lake and Big Spring serving as vital hubs in an otherwise arid environment.
