1961 Map of San Geronimo

About this map

San Geronimo sits at the eastern edge of the mountainous terrain where Tecolote Creek winds through the landscape. This 1961 field-checked survey highlights the transition from the high peaks of the Santa Fe National Forest to the ranching and settlement areas of San Miguel County. Genealogy researchers can identify the local Cem and specific homesteads like Shearer Ranch or the San Geronimo Cabin. The geography is defined by a dense network of watercourses and canyons, including San Pablo Creek and Tres Hermanos Canyon. Industrial and utilitarian activity is evidenced by a Mine and a Lookout Tower positioned on high ground near Barillas Peak. The map also delineates a significant Grant Boundary that bisects the region, reflecting the complex land ownership history of northern New Mexico.
