2010 Map of La Segita Peaks

About this map

Volcanic geology and industrial mineral extraction define this section of Rio Arriba County. The landscape is marked by prominent natural features such as the Wissmath Craters and the towering summits of La Segita Peaks. This 2010 survey highlights a significant hub of mining activity in the southern region, particularly surrounding the No Agua Peaks. Industrial operations including the Johns Manville Perlite Corporation, United Perlite, and the Johns-Manville Mine suggest the area's importance for perlite production during the early 21st century. Drainage patterns are dominated by the Arroyo Punche, which flows through the northern reaches near Punche Lake, and the winding Arroyo Aguaje de la Petaca to the southwest. Away from the concentrated mining sites, the terrain remains largely defined by open expanses and remote forest access via routes like F R 418.
