torrent that once occupied this area. One of the most unusual fossils ever found in the Columbia Plateau is a mold and a few bones of a small rhinoceros.
The Washington State Parks and Recreation Commission has constructed an Interpretive Center at Dry Falls which houses exhibits and tells the story of the creation of this geological phenomenon. The building overlooks the giant precipice and affords a magnificent view through
picture windows. The park schedule is from May through September, 10 am - 6 p.m. daily.
The Grand Coulee, of which Dry Falls is a central feature, has been designated a Registered Natural Landmark by the U.S. Department of the
Interior. A bronze plaque to this effect is located in the small vista house adjacent to the parking area.
Recreation - Activities at the park include visiting the interpretive center, viewing the scenery and hiking to the Lake Lenore Caves.
Climate - The climate of Washington varies within each region. The Cascades split the state and alter the weather patterns. The terrain east of the mountains, which includes the Dry Falls Interpretive Center, receives approximately 12 inches of rainfall per year, generally much less than west of the mountains. Since the area east of the mountains is landlocked, temperatures in this region are lower during the winter months. Frequent winds coming down from the mountains also contribute to the low temperatures of eastern Washington.
Dry Falls State Park, in south central Washington, is located 7 miles southwest of Coulee City, on state route 17.
