Now this is a site to behold, Salvation Mountain in Niland, California. Niland's about an hour-and-a-half drive from Palm Springs, California. It's worth the trip because the size and scope of the place is beyond imagination.
The mountain is made of adobe mixed with straw, materials developed after the first mountain fell down.
There are so many photo ops here that you should bring all the cameras you have. You can experiment with all kinds of settings here from wide to narrow apertures to long and short focal lengths. In the inside areas, you'll need a tripod.
Don't miss this place if you're in the Salton Sea area.
