MURAL PHOTO'S The idea of a historic mural honoring 100 years of logging in Priest River was conceived nearly ten years ago by the Priest River Chamber of Commerce. When completed, it will span 1,000 feet, one of the longest murals in the United States. While it is still a "work in progress",the mural project is on the home stretch.. All the panels have been painted by the mural artist Diana Schuppel and 95 of the 160 panels that will be needed have been erected. The original mural layout was created by Lynn Guier.
