Leonard Knight is the creator of Salvation Mountain, 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. He’s been living in the desert there and working on his monument for nearly 27 years, but late last year Knight was placed in a long-term care facility for dementia. Concern has been raised for the future of this amazing piece of art without his constant attention and maintenance. If you haven’t visited this incredible place, now is the time before it’s the end of an era.
