The Continental Divide zigzags across this high-altitude landscape, separating the headwaters of the Navajo River and Rio Chama from the South Fork Conejos River drainage. This 1957 field check records a sparsely settled wilderness where early industrial and ranching interests carved out a presence. The Gramps Oil Field stands as a notable industrial landmark amidst the massive peaks of the Chalk Mountains, while the Tierra Amarilla Grant Boundary marks a historical property line dating back to Spanish and Mexican land grants.
