The high alpine headwaters of the Rio Grande dominate this high-altitude landscape in the mid-1960s, where the river carves through Box Canyon and Road Canyon Reservoir No 2. This survey illustrates a backcountry defined by significant hydrologic and elevation markers, including the jagged Knife Edge and the sweeping Continental Divide that separates the Rio Grande National Forest from the San Juan National Forest. A network of high mountain lakes and reservoirs, such as Trout Lake, Ruby Lake, and Fuchs Reservoir, are connected by a system of historical transit routes including the Stock Driveway and various Pack Trails. Notable landmarks like Chief Mountain and River Hill provided essential orientation for early 20th-century travel through the San Juan Mountains, while the River Hill Campground highlights the area's established role for outdoor recreation during the post-war era.
