1990 Map of Livingston Hills NW

About this map

Kofa National Wildlife Refuge dominates the eastern landscape of this 1990 provisional survey, capturing a stark desert terrain defined by the Livingston Hills. The map details a transition between La Paz and Yuma counties, marked by the prominent Base Line and a network of arid drainage systems including Tyson Wash. This region reflects a landscape managed for conservation and resource transport, evidenced by the presence of a Pipeline cutting across the northern flats and the designation of the Palm Canyon Road in the south. Surveyors identified specialized water management features like the Guzzler and established geodetic control points at Kofa North Base and Kofa South Base, providing essential data for navigating this portion of the Sonoran Desert.
