About this map

The Baca Location No 1 Grant dominates this landscape, revealing a massive high-altitude caldera environment defined by vast open valleys and volcanic domes. Complex hydrological networks are visible as San Antonio Creek and Jaramillo Creek wind through the meadows, while the East Fork Jemez River emerges in the southern reaches. The map documents the overlap of significant land jurisdictions, including the Santa Clara Indian Reservation and Santa Fe National Forest.

High-elevation landmarks like Cerro Toledo and the Sierra de los Valles flank the central basins. Cultural features are sparse but significant, featuring the Pajarito Mountain Ski Area near the border of Sandoval and Los Alamos counties, and the small settlement of Camp May. This mid-century survey, updated in the early 1990s, captures the transition of the Valles Caldera from a remote private grant toward its eventual public significance, showing the primitive road network at Puerta de Trasquilar and Puerto de Abrigo.
