Yeager Rock, a glacial erratic on Waterville Plateau, Washington, USA

Boulder Park National Natural Landmark along with the nearby Natural Landmarks McNeil Canyon Haystack Rocks and Sims Corner Eskers and Kames comprise several of the best examples of Pleistocene ice stagnation landforms in Washington. Features include numerous glacial erratics near and on the terminal moraine. Boulder Park is located on the Waterville Plateau of the Columbia Plateau in north central Washington state in the United States. The boulders provide important evidence for glacial erosion and transport, as well as marking the direction of movement and the terminus of the Okanogan lobe on the southern margin of the Cordilleran ice sheet during the last glaciation.[1]
