Dry Falls (above), a basalt face 400 feet deep and 3.5 miles long in north-central Washington, was anything but dry 15,000 years ago. Flood water from a collapsed ice dam in Montana turned these cliffs into what is thought to be the largest waterfall ever to exist. Five times wider than Niagara Falls. Once the ice sheet obstructing the Columbia River melted, the river returned to its normal course, leaving the Grand Coulee and the falls dry. I peered over the edge during a two-day photo shoot on the Waterville Plateau. Dry Falls, located 7 miles southwest of Coulee City, was impressive. So were the abandoned homesteads and farms I photographed in the wheat lands off Highway 2.
