1964 Map of Ludwig Mountain

About this map

The Los Pinos River carves through this corner of the San Juan National Forest in southwestern Colorado, defining a landscape shaped by water management and high-altitude terrain. Irrigation is central to the valley's development, evidenced by an extensive network of gravity-fed water systems including the Farrell Ditch, Sullivan Ditch, and Thompson-Epperson Ditch which trace the contours along the river banks. These engineering feats speak to the ranching and agricultural history of the region below the rugged peaks.
