The dangers attendant on speleology have perhaps not been sufficiently emphasized. In one particularly gruesome incident, a spelunker dived into a cave pool, passed unawares through a subterranean passage, and emerged from the pool into an enclosed grotto. Being unable to find his way back with the pool disguising his whereabouts from the search party, he starved to death in the darkness.
