Also i think that the scene with the p-bear on the desert is just another dharma site.

The plane in the water was staged, obviously, by dharma to put all this to rest so they could go in without any attention.
Regardless of what that dig site is all about, the collar on the bear's neck came from the Hydra Station, that is the island where Sawyer and Kate were hanging out in cages.
