San Juan National Forest defines the rugged geography of this corner of southwest Colorado, where high ridges and managed watersheds dominate the landscape. The terrain is anchored by notable peaks such as Narraguinnep Mtn and Elston Mtn, with the long stretch of Narraguinnep Ridge and Hosea Ridge framing deep draws and canyons. This 2019 survey documents a complex network of ranching infrastructure and water management, evidenced by the high density of small water bodies like Salter Reservoir, Barney Reservoir, and Young Reservoir. Local names like Glade Ranch and Mccomb Ranch hint at the area's agricultural footprint within the protected forest lands. Tracing the numerous forest roads, such as Glade H and Glade A, reveals a landscape engineered for resource access, connecting natural features like Narraguinnep Spring and Indian Spring to a series of man-made catchments that support the region's ranching economy.
