The Puyallup River in Pierce County, Washington flows about 45 miles from its source on Mount Rainier to Commencement Bay at Tacoma. It is joined by the Carbon River north of Orting and the White River at Sumner. Its valley's 150,000 residents are at risk from lahars should Mount Rainier erupt--for this reason, the United States Geological Survey has installed a lahar warning system.
