Bighorn Peak and the high high-altitude terrain of the New Mexico-Colorado border define this landscape, where the Carson National Forest and Rio Grande National Forest meet. Small settlements like Sublette and Big Horn sit near the northern boundary, while San Miguel appears further south along the Rio de los Pinos. The map reveals a high-country network of water management through numerous cattle tanks and springs, including Casas Tank, Ojito Spring, and the curiously named Alive Number Two Tank. Geographically, the area is dissected by deep canyons and washes such as Canon Florentino and Canada de Oso, while the San Miguel Cem serves as a grounded point of local history for genealogists researching families of the Rio Arriba area. Modern access is marked by several Forest Development Roads, including FDR 87, which traverse the high plateaus and ranching lands.
