Lake Lawrence erratic
Boulder in Thurston County, Washington
From Wikipedia, the free encyclopedia
The Lawrence Lake erratic is a glacial erratic boulder near Lake Lawrence in Thurston County, Washington.[1][2] The boulder is about 15 feet (4.6 m) tall. Lake Lawrence itself was formed when the Vashon Glaciation created most of the topography seen in the Puget Sound region.[3] The erratic is one of the southernmost in the Puget Sound region, near the limit of the Yelm lobe of the Vashon Glacier in the Rainier area.[4]
