Cumbres and Toltec Scenic RR winds across the high terrain of the New Mexico and Colorado border, crossing through Cumbres Pass at the western edge of the quadrangle. This mid-1990s landscape is defined by the intersection of forest management and historical land grants, particularly the sprawling Tierra Amarilla Grant. The drainage network is dominated by the headwaters of the West Fork Rio Brazos and East Fork Rio Brazos, which converge south of the Brazos Meadows. The map illustrates the seasonal grazing economy of the high country, evidenced by locations such as Burn Cow Camp and Rivera Cow Camp. These camps, along with numerous 4WD tracks, indicate a land used for ranching and resource management within the Carson National Forest and Rio Grande National Forest. Small alpine water bodies like Dean Lake and Mesa Lake sit perched near Osier Mesa, surrounded by an intricate system of springs.
