Salvation Mountain is a visionary environment covering a hill in the Colorado Desert, north of Calipatria, northeast of Niland near Slab City, several miles from the Salton Sea. It is in Imperial County, California.
The artwork is made from adobe, straw, and thousands of gallons of lead-free 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, though its philosophy was built around the Sinner's Prayer.
The Folk Art Society of America declared it "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".
