About this map

The San Juan River valley serves as the primary artery for settlement and transport in this corner of San Juan County, where the village of Blanco is established on the northern bank. The landscape is defined by the sharp contrast between the irrigated river corridor and the high, arid desert terrain of Manzanares Mesa and Harris Mesa. Local history is centered around the Saint Rose Cem and the network of canyon systems like Muñoz Canyon and Armenta Canyon that cut through the plateaus.

Deep desert topography is recorded with precision, showing the vast drainage of Cañon Largo and the prominent landmark of Dziltnsahah. A complex web of county and forest roads, including Co RD 4800 and Sullivan Rd, provides access across the mesas, connecting the river valley to the more remote canyons like Medina Canyon. This map captures the modern distribution of rural homesteads and agricultural plots against the expansive New Mexico badlands.
