Formation
of the cavern began about 25 million years ago. It now
soars to the height of a 12- story building and stretches
the length of a football field. Care is taken not to
disturb the natural habitat of the wild animals that
dwell here. Sea lions gather in this natural
amphitheater, usually during fall and winter. In spring
and summer, they breed and have their young on rock
ledges just outside the cave.
