If you have seen the movie "Into The Wild", the shots of the nudist hippies at the hot springs and the conversations on the rocky mountainside between the old man and the main character, were all filmed in the "Cove" region of Ocotillo (behind Blow Sand Hill). We were out there camped at the Cove (I think it was Thanksgiving weekend?) two years ago, and they had the hot springs set, all set up. There were a bunch of old cars and hippie busses, and they had lined a hole with plastic and filled it with water to make it look like a springs. They had left a security guard behind to keep folks from messing with the set, but the poor guy didn't have any food! I guess the union rules say they have to feed them three times a day, but somehow this poor guy got overlooked. So, we shared our meals and campfire with him, until somebody came and finally relieved him a couple days later. The set is supposed to look like "Oh My God Hot Springs", which was originally miles to the east, closer to Salton City. The springs was closed by the county years ago (capped off and buldozed over), I guess because of the "unsavory element" that it attracted (????). You can clearly see the fence behind the Cove in some of the shots, and Blow Sand is visible in the background of some of the mountainside shots. (This mountainside, is a favorite of a lot of rock crawlers, myself included!) Also, there are scenes at Slab City and Salvation Mountain, which is on the other side of Salton Sea, near Nyland.
