The artwork is made from adobe, straw, and thousands of gallons of paint. Salvation Mountain was created by local resident Leonard Knight (1931–2014). It encompasses numerous murals and areas painted with Christian sayings and Bible verses.
The Folk Art Society of America declared it a "a folk art site worthy of preservation and protection" in the year 2000. In an address to the United States Congress on May 15, 2002, California Senator Barbara Boxer described it as "a unique and visionary sculpture... a national treasure... profoundly strange and beautifully accessible, and worthy of the international acclaim it receives".
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 has been working to protect and maintain the site.
