About this map

Hyder sits at the southern edge of the desert floor, where the Southern Pacific railroad cuts a straight line through the arid landscape of Hyder Valley. This 1965 field-checked survey reveals a territory defined by its hydrology and infrastructure, with the Yuma Co Maricopa Co boundary line running through a series of extensive desert washes. To the southwest, the Agua Caliente Mts rise sharply from the valley floor, providing a stark topographical contrast to the surrounding flats.

The map documents a network of utility and transport, including a significant Pipeline and numerous routes marked as Jeep Trail that connect isolated points like Main Camp Well. The drainage patterns of Columbus Wash, Nottbusch Wash, and Agua Caliente Wash illustrate the complex natural irrigation of the Arizona desert, highlighting how geography dictated the placement of early settlements and rail siding locations.
