Salvation Mountain is an art installation covering a hill north of Calipatria, California, near Slab City and just several miles from the Salton Sea. It is made from adobe, straw, and thousands of gallons of paint. It was created by local resident Leonard Knight, and encompasses numerous murals and areas painted with Christian sayings and Bible verses. In December of 2011, Knight was placed in a long-term care facility in El Cajon for dementia. Concern has been raised for the future of the site, which requires constant maintenance due to the harsh surrounding environment. Many visitors bring paint to donate to the project, and a group of volunteers have been working to protect and maintain the site. Photo by Carol Highsmith.
