1955 Map of Glamis

About this map

The Southern Pacific railroad corridor cuts a sharp diagonal across this arid landscape, serving as the primary lifeline between the isolated outposts of Glamis and Ruthven. This 1955 survey, with photorevisions through the late 1970s, captures the stark geography of the Sand Hills and the extensive Imperial Sand Dunes Recreation Lands. The terrain is defined by complex dune formations and the broad, open expanse of East Mesa, where a network of Jeep Trails and several prominent Dikes provide the only significant landmarks beyond the steel rails. The mapping reflects a region defined by its harsh environment and the infrastructure required to traverse it, offering a clear record of the transportation and recreation patterns in this corner of the California desert.
