1971 Map of Canon Pedroso

About this map

Pedroso Creek defines the primary drainage of this arid terrain in northeastern New Mexico, winding through the Cañon Pedroso as it descends through the mesa country. This 1971 survey, based on aerial photography from the previous year, captures a transition in the high plains landscape between the Mora and Las Vegas land grants. The map is primarily a study of topography and relief, showing the stark contrast between the flat upland plains and the deeply incised canyon systems that characterize the San Miguel County region. Sparse development and minimal infrastructure suggest a landscape dedicated to large-scale ranching and grazing, where water sources like the creek were the essential focal points for land use and movement.
