1996 Map of Sierra Alta

About this map

Rio Grande waters dominate the eastern edge of this landscape, cutting through the Rincon Valley where the river is accompanied by irrigation infrastructure like the Rincon Lateral and the Rincon Private Drain. This area reflects a mid-century ranching and transit corridor, highlighted by the Tonuco Bridge crossing and various established family holdings such as the Haynor Ranch and Hermitano Springs Ranch. To the west, the terrain rises sharply into the high ground of Sierra Alta and Sierra Kemado, dissected by numerous dry washes including Broad Canyon and Angostura Arroyo. The presence of scattered tanks like Hatchler Tank and Brewster Tank illustrates the critical role of water management in sustaining livestock across this arid New Mexico interior. For those tracing local history, the map includes details such as a Mine and a small Cem near the river valley.
