I watched some survivalists bury their caches and they proudly filmed it for YouTube. One guy said he was going to be smart and not reveal even the general location of where he buried it. He took great pains in concealing and covering his tracks. But then he proceeded to pace off the location of the cache from X tree and Y bush.

So I asked him - if a fire were to rip through the area, could he find his cache again? >>crickets<<. He had no GPS coordinates, only visual reckoning. I wonder if he ever found that cache again (it was a big chest buried several feet down and must have been worth a couple of grand).
