Agricultural and aeronautical infrastructure define this mid-1950s landscape in Grant County. The area is marked by a complex system of water management, including a prominent Wasteway and multiple Canal segments like the W-20 that supported the region's developing irrigation needs. This survey reflects a period of modernization where the traditional White Trail Road and Morrison Road intersect with newer utility corridors like a major Pipeline. High-elevation landmarks such as VABM Blythe 1360 provided critical reference points for surveyors, while the Ephrata Radio Range Station and an Airway Beacon signify the area's importance to regional aviation routes. The map provides a detailed view of the terrain's transition, evidenced by several dry wells and the extensive network of earthen structures like the Levee protecting these low-lying lands.
