Exploring Caves — Suit up with a helmet and light, and take Cave Crawl(爬行). Bring your own knee pads. Learn about equipment used by cavers and rules for safe cave exploration. Spend the morning viewing stalactites(钟乳石)— rock formations that hang from the ceiling — and their opposites, stalagmites(石笋).
Cave Alive — Take a look and learn about bats, salamanders, and other interesting creatures that grow up in caves. See crickets, crayfish, and even beetles. Learn why bears like to live in caves.
Fossils(化石)— Learn how remains of ancient plant and animal life became set in rocks, and discover how they provide clues about Earth’s history. Examine fossils in the cave.
Caves — Learn how changes in underground rock formation cause openings and caverns to develop. Find out how acidic water dissolves(溶解)limestone to create caves.
Manners — Learn how to preserve and protect beautiful, interesting, and educational caves. Learn why bats should not be disturbed when they are hibernating. Never go caving alone. Take nothing but pictures; leave nothing but footprints.
