WEll, I am brand new here, but this story is one I grew up with. I was raised in the Imperial Valley, and my Grandparents homesteaded in the Cochella Valley. Anyway, Oroblanca, you are right, and Kimberly, sorry but you are wrong. Since I grew up there and also had a lot of input from the older generations, many things may not have been general knowledge, one, is if you travel up the west side of the Salton sea, you can see water marks on the mountains, divided by by some colored in betweens, this is the high and low tidal marks made on the mountains, also if you go up to these you will find old indian fish traps, made to take advantage of the tides. These two things indicate a connection to the sea. If it were a landlocked lake, this would not have happened with only a short time connected to the sea. It takes many years of connection(hundreds if not thousands) to make such marks. And indeed it did flood in 1907, it was history I had to study. But one other thing, at the bottom of the Salton sea is a salt mine, this accumalation of salt only happens when there is a dried sea or ocean. Ask a geologist. But as stated it flooded and has had agricultoral runoff ever since, the two rivers flowing into it are the New River and the Alamo. At one time as a teenager I worked for a man named Harry Arrington, he had a"country store", and loved treasure hunting, as well as my family, so I got paid to go and look for things, the best of my recollection we went to a place called "Coyote springs, it was supposed to be close to there according to Harry. Didn't find it, but more likely as one post said, the superstitions was a more likely spot. If I ever get to retire and do treasure hunting again, I will spend my winters down there, I have knowledge of several treasures in the IV and south of the border. Everyone good hunting!!jim
