1965 Map of Trimble Point

About this map

The Dolores River winds through this mid-1960s landscape, carving a deep path south of Salter Canyon and through the San Juan National Forest. The map documents a complex water management system essential for this high-altitude environment, featuring numerous small reservoirs and springs such as Hoppe Point Reservoir, Dunham Reservoir, and Campbell Reservoir. A network of irrigation channels, including the Lone Pine Lateral and Main Canal No 2, suggests the agricultural efforts on the flatter benches above the river canyons.
