Whether it's a troll cave, a man cave, or even the cave of wonders, these mysterious underground hollows are home to all sorts of interesting creatures. Take the caves in Montana's Glacier National Park, for instance. Aside from bats, wood rats, and spiders, you'd be surprised at what you might find there—like a dedicated group of teens from Bigfork High School's Cave Club. Bigfork's Cave Club was founded in 2007 by Hans Boderman, a cave researcher and science teacher at the high school. He started the Cave Club because of his interest in local science and nature concerns. It grew into a great way to show students how they can make a difference. Students joined for the adventure of going into caves. They stayed when they realized the impact they were having on the world around—and below—them.
