Here's a night photo with the crime scene under lights ... placed beside a map from the entrance to the park. The little box is in both photos (in the map image, it's easier to recognize the little box from the shadow). I've marked the little box - perhaps where a fee is taken - with an A. That is most likely where the body was found, because that appears to be where police were working late at night. This is also where the Command Center was set up before being moved to the Beach Access area in the park.
Perhaps dry creek would be better described as ditch.
