Dry Falls began near Soap Lake to the south and also ate away the landscape until it reached its current site. After the waters receded and the Columbia River returned to its original route around the plateau, Dry Falls was left high and dry. And what remains, state parks officials describe as the skeleton of one of the greatest waterfalls in geologic history. Highway 17 presents a spectacular view. 6 p.m. daily, offering various displays on the history and geology of the falls and the region.
Admission is free.
The center is wheelchair accessible. Rest rooms and a few picnic tables also are available. However, for a shadier picnic spot, drive about one mile south to Sun Lakes State Park, where you can cool off with a swim in the lake, rent a paddle boat or stay overnight in a cabin. The park's resort is operated by a private concessionaire. About 10 miles south of the interpretive center, just off the highway, a primitive trail leads to some caves carved out by the ice-age flood waters.
