Swing Rock is a giant boulder that is part of the Snoqualmie Tribe’s oral history of the Snoqualmie Valley. Their oral traditions say that the giant rock between North Bend and Snoqualmie are the petrified remains of a rope swing that stretched from Mt. Si to Rattlesnake Ridge. Early pioneers named it Quarry Rock and decimated this culturally important landmark through excavation and quarrying for road building. The excavation has continued for many years and the scars of this destruction are still visible today.
