I have spent a good deal of my life climbing mountains and exploring caves. Whenever we pass a cave, we cannot resist spending the time to go exploring or take the tour. We recently went to the Crystal Cave in Sequoia National Park. It turned out to be a very nice cave at the end of a longer than usual walk. Taking pictures in caves in an entirely different matter. The pictures seldom come out like you hope, but this is one of Crystal Cave that did come out well.
