About this map

Rosa and its landmark Santa Rosa Ch sit at the confluence of the San Juan River and Sambrito Creek, a region defined by agricultural irrigation and burgeoning energy exploration in the mid-1950s. The landscape is carved by significant drainages such as Bancos Canyon and Cottonwood Canyon, while the higher elevations of Miller Mesa overlook the river valley. Irrigation infrastructure is prominent, featuring the Mentzel Ditch and Miller Ditch, which supported local homesteads before the landscape was altered by later water management projects.

The energy sector's early footprint is visible through several Gas Wells scattered across the northern sections. Transportation in this corner of Rio Arriba County relied on a network of unimproved roads and a small Landing Strip, highlighting the area's isolation. This survey captures the traditional San Juan River settlements and their early 20th-century irrigation systems just years before the landscape underwent massive changes.
