Tour hugs the south side of the Puyallup River, which has its source in Puyallup Glacier on Mount Rainier and is fed by the North Mowich and South Mowich glaciers. The Carbon River and the White River via the Stuck River also flow into the Puyallup. The highway cuts across thousands of acres of daffodil, berry, and truck farms. On distant hillsides may be seen occasional silver-fox farms, enclosed with close-meshed wire fences.
