There’s a cool old documentary about the place called Plagues and Pleasures on the Salton Sea, narrated by John Waters. It goes into the history of the place and shows a little of how dilapidated and decayed it now is (well, now was, when it came out in 2006).
It tries to livin up the modern day stuff by showing some of the “colorful” characters who lived there. I have to imagine there was a lot not being said, and I’m sure 20 years of further decay have not made it the friendliest and funnest place to be.
Edit to add: Apparently some enterprising soul has uploaded it to YouTube: youtu.be/8TjGAWxL23c
