2014 Map of Poison Canyon

About this map

The high plateau of N Elk Ridge dominates this San Juan County landscape, part of the Manti-LaSal National Forest. In this 2014 survey, the intricate drainage patterns of the Colorado River basin are evident through deep incisions like Deadman Canyon, Peavine Canyon, and Drift Trail Canyon. The map reveals a series of named grazing grounds and natural landmarks including Redd Pasture, Poso Pasture, and the notable Queens Arch to the southwest. Human presence is sparse, primarily defined by the winding route of Sweet Alice Rd and established water sources such as Sego Spring and North Notch Spring. Prominent geological features like Steamboat Point and Chimney Park rise above the canyon floor, illustrating the characteristic erosion of the Four Corners region before it descends into the larger systems beyond the quadrangle.
