Swing Rock, a giant boulder, 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 is 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 continued for many years and the scars of this destruction remain visible today.
