The position of this vintage 1960s station wagon at the remote and roadless northern side of the Bahia is a fascinating mystery that can motivate creative story telling. The most plausible explanation might be that it was driven to the top of Bahia ridge when the preserve was still a mostly grass-covered ranchland, and somehow rolled down the hill and crashed. The trees that grew around it after grazing ended seem to be lifting the wreck up as they grow and grab the metal in various places with their bark.
