Alamosa River drainage and the small settlement of Jasper define this high-altitude section of the Rio Grande National Forest at the turn of the 21st century. The map captures a landscape shaped by mining history and early forest management, where a legacy Mine and a Ranger Station sit near the steep slopes of Cornwall Mountain. The hydrology of the region is notably complex, featuring high-country water bodies like the San Francisco Lakes and Silver Lakes, alongside a dense network of gulches including California Gulch and Rhodes Gulch. A primitive transportation network of trails, such as the Fitton Trail and Ranger Trail, provides the primary access through the high passes like Blowout Pass. This survey illustrates the rugged interface between the Rio Grande and Conejos county line, where natural landmarks like Cornwalls Nose serve as prominent navigational markers for those tracing historical land use and early resource extraction.
