Why to abandon the ship on the east side of the Salton sea ? Only fools would tried to return from the side of the fresh mud and desert . The only logic decision would be the return to be done from the west side , the mountains .
To be trapped the ship inside the land , the Salton sea should be under 46 ft altitude . I made a map in GE which shows the margins of the Salton sea at 46 ft altitude ( blue colour ). The red line is in the Delta ( Mexico ) region and is the highest point in the wash from the lower point of the region . So , if the Salton sea is under 46 ft , then there is a sand barrier which avoid to pass to the ocean , and if the Salton sea is over 46 ft , then falls on the other side to the ocean .
Now , what should do a logic and smart captain ? IMO , he would try to find o closer and safer way to the west side of the Salton sea and to hide the ship if this is possible for a future return .
What would be the closer and safer way ? IMO , at the north end of the mountains from the west side ( green colour ) , because if they would passed the mountains at the first place ( red line ), they would found on the other side water and mud .
IMO , at the green circle region ( see the second GE image ) , is the only place where they could hide the ship , because there was a little gulf which was surrounded by high hills .
This could be the real story of the Pearl Ship .
