Hat Rock State Park is a state park in the U.S. state of Oregon, administered by the Oregon Parks and Recreation Department. The park is located off the east side of U.S. Highway 730 in Hermiston,[2] on the south shore of Lake Wallula behind McNary Dam on the Columbia River.[3]

Flood basalt

Anchor, a landmark in the Park

Hat Rock is a geological formation that, along with another outcropping rock in the park called Boat Rock, are thought to be exposed remnants of a 12-million-year-old basalt flow. Floods from the Ice Age eventually left these bedrocks, as well as others along the Columbia River Gorge exposed at the surface of the Earth.[4] It is 70 feet (21 meters) high.
