2017 Map of La Plata
USGS Topo · Published 2017About this map
The La Plata River corridor in San Juan County reveals a landscape defined by an intricate network of irrigation and desert water management. Settlements like La Plata are surrounded by engineered waterways including the La Plata Indian Ditch, Highland Park Ditch, and the Pioneer Ditch, which redirect flow from the river and various arroyos to support the arid plateau. This high-desert terrain is marked by significant geological features such as Barker Dome and the Cinder Bluffs, while numerous dry washes like Dawson Arroyo and McDermott Arroyo carve through the mesa country. Evidence of local history and genealogy is preserved at the LaPlata Cem and Greenhorn Cem, providing points of reference for the families who settled this region near the Colorado border.
