Hat Rock State Park, located off U.S. Highway 730 nine miles east of Umatilla, lies on the south shore of Lake Wallula behind McNary Dam on the Columbia River. Hat Rock was the first distinctive landmark passed by the Lewis and Clark Expedition on their journey down the Columbia, and is one of the few remaining sites not underwater.
