About this map

Royal City stands as the primary hub on the Royal Slope in this mid-1980s look at Grant County's agricultural interior. The landscape is defined by the sophisticated Columbia Basin Project irrigation works, most notably the West Canal and the Royal Branch Canal which feed the local farming economy. Between the high ridges of the Frenchman Hills to the north and Crab Creek to the south, the map reveals a meticulously managed environment.

Technical infrastructure, such as the Blythe Watermaster Headquarters and the Low Gap Pumping Station, highlights the engineered nature of the terrain. The presence of the Desert Habitat Management Area and Crab Creek Habitat Management Area shows how public lands were designated to preserve local ecology alongside intensive agriculture. Geologic features like Red Rock Coulee and Cash Butte provide clear landmarks within the transition from hills to valley floor.
