The above photo showing a close-up of the escarpment at Latourell Falls, in the Columbia River Gorge east of Portland, Oregon, was taken on July 29, 2004. Numerous waterfalls, such as this one, have cut through lava deposits hundreds of feet thick. This photo shows clearly the classic columnar basalt formation that formed when the lava cooled several million years ago. The white laser-like vertical band is the waterfall -- Latourell Falls plunges nearly 250 ft (about 76 m).
