South Yuba River?

This picture of the South Yuba River was taken on Hampshire Rocks Road off Interstate 80 at Soda Springs, California.  The South Yuba River is a 65 mile long tributary of the Yuba River along the Interstate 80 Highway.  One would think it is a watering hole from the photo.  When someone named the road Hampshire Rocks Road, I would say it was an understatement.
