The La Posa Plain is a wide, generally flat plain in western Arizona near the Colorado River and is on the west and northwest border of the Kofa National Wildlife Refuge. The plain lies to the east of the Colorado River Indian Reservation and east of the Dome Rock Mountains. Quartzsite, Arizona lies on the western part of the plain, which crosses both Interstate 10 and U.S. Route 95.
