About this map

Dahlia sits at the northern edge of this high-altitude landscape, situated where the terrain drops into the prominent Cañon Blanco. This region is defined by a complex network of drainage systems and seasonal water sources, which were critical for the ranching and agricultural efforts of San Miguel County. The map details a sophisticated system of earthen tanks, such as Larranaga Tank, Lake Tank, and Laquinita Tank, designed to capture runoff in a landscape where permanent water is scarce.

Southward, the topography rises toward Potrillo Hill, while the ephemeral Potrillo Creek and Potrillo Draw snake through the central valleys. This survey illustrates the tri-county intersection where San Miguel, Guadalupe, and Torrance Counties meet. The presence of named canyons like Cañon de la Luvina and Cañon de Padre alongside established routes such as Co Rd C115 and Western Run Rd provides a clear view of the modern infrastructure supporting this rural New Mexican territory.
