Mining claims and alpine drainage systems dominate this corner of Taos County, where the southern reaches of the Costilla Reservoir sit near the Colorado border. The landscape is defined by the high-elevation geography of Anderson Park and Valle Vidal, with a dense concentration of historical mining operations located in the southwestern quadrant. Prospects such as the Midnight Mine, Edison Mine, and Cashier Mine are clustered near Lagunita Saddle, reflecting an era of intensive mineral exploration in the Sangre de Cristo range. The map reveals a network of canyons including Chuckwagon Canyon and Fernandez Canyon that feed into the major watercourses of Costilla Creek and Comanche Creek. Temporary settlements and seasonal camps like La Cueva Camp and Clayton Camp are situated along these creeks, while the presence of the Snyder Tunnel and Keystone Tunnel points to the subsurface industrial heritage of the region.
