About this map

Comb Ridge dominates the eastern landscape of this San Juan County region, forming a massive monocline that dictates the local drainage patterns. Parallel to this geological spine, Comb Wash and Butler Wash flank the ridge, providing the primary north-south corridors through this arid terrain. The map documents a network of rural roads, including Comb Wash Rd and several county routes such as Co Rd 236, which navigate the complex topography of canyons and plateaus.

Notable landmarks such as Snow Flat and the winding passage known as The Twist indicate the challenges of early travel in the area. Water sources remain critical in this environment, with Sweet Springs and the drainage of Fish Cr providing rare relief. Significant geographical features like Mule Canyon and Stevens Canyon carve into the western and eastern edges of the sheet, illustrating the erosion-defined character of the Colorado Plateau near the turn of the 21st century.
