About this map

Alkali Flat dominates the arid basins of this high-desert landscape on the border of Sierra and Doña Ana counties. The terrain is characterized by ephemeral water sources and mineral-rich depressions, most notably the broad expanse of Big Salt Lake and the nearby Alkali Spring. These features suggest a challenging environment where water management was critical, evidenced by the presence of Mason Tank and CCC Tank, which likely served as livestock watering holes or conservation projects.

Modern infrastructure is limited to specialized transit corridors like WSMR P Route 6 and WSMR S Route 304, indicating the area's inclusion within a military testing range. The natural drainage of Salt Cr cuts through the eastern portion of the sheet, providing a rare topographical break in an otherwise expansive, level territory where survival depended on localized water catchments and seasonal springs.
