Whitstran and Gibbon anchor this mid-1960s landscape, situated along the curve of the Yakima River where the Northern Pacific railroad follows the valley floor. The map illustrates a complex agricultural water system essential to this arid region, featuring the Sunnyside Canal, an Aqueduct, and a Siphon that move water across the Yakima's northern banks. To the south, the terrain rises sharply into the high ground of Gibbon Ridge, where the landscape shifts from irrigation-fed fields to a network of upland roads and trails.
