Situated in the heart of the United States farming and agricultural region, the cities of Omaha, Nebraska, and Council Bluffs, Iowa, are evident in this west-southwest-looking, low-oblique photograph. Visible is the south-flowing Platte River as it turns eastward to join the south-flowing Missouri River 20 miles (32 kilometers) south of Omaha, one of the largest livestock markets and meat processing centers in the world. Apparent midway between Omaha and the Platte River are the runways of Offutt Air Force Base, the headquarters of the U.S. Air Force Strategic Air Command.
