1983 Map of West Fork Rio Brazos

About this map

Osier Mesa and the sweeping high country of Tierra Amarilla dominate this 1980s landscape along the border of Colorado and New Mexico. This region is a complex intersection of administrative and natural boundaries, where the Rio Grande National Forest meets the Carson National Forest. The drainage patterns are defined by the West Fork Rio Brazos, which is fed by numerous tributaries including Arkansas Creek, Apache Creek, and Wolf Creek. At the northern edge, Mesa Lake sits near the tri-county junction of Archuleta, Rio Arriba, and Conejos. This map captures the area as it was surveyed in the late 1970s and early 1980s, documenting a terrain shaped by high-elevation watercourses and the seasonal grazing lands of Brazos Meadows.
