The Snake River forms a winding border between Idaho and Oregon on this 1951 survey, revised with 1974 aerial data to show the expanding footprints of Payette and Ontario. This riverine landscape is defined by its complex irrigation network, including the Washoe Canal and Pioneer Ditch, which support the agricultural valley between Snow Mountain and the water. The map documents a significant era of post-war development, visible in the growth of Fruitland and the establishment of institutions like Treasure Valley Community College.
