1965 Map of Picacho SW

About this map

The Colorado River winds through the borderlands of Imperial Co and Yuma Co in this mid-1960s study of the desert riverfront. The landscape is defined by the contrast between the fertile river corridor of the Imperial National Wildlife Refuge and the arid, broken terrain of the Trigo Mountains. Notable historical sites are recorded along the banks, including Nortons Landing (Site), Hoge Ranch (Site), and Nommel Place (Site), indicating earlier settlement patterns before the area was primarily designated for conservation and recreation.
