The Lawrence Lake erratic is a glacial erratic boulder near Lake Lawrence in Thurston County, Washington.[1] The boulder is about {{convert|15|ft}} 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.[1] References1. ^{{citation|title=Geologic Map GM-56: Geologic Map of the East Olympia 7.5-minute Quadrangle, Thurston County, Washington|authors=Timothy J.
