Caving is a tricky business and takes a lot of preparation. In addition to arming yourself with coveralls, helmets, lights, ropes and supply of the good batteries, you have to be ready to do a fair amount of scrambling, stooping, crawling and squeezing through tight places. But in addition to its challenges, caving has its rewards when you uncover thousands of years of geologic history. Unfortunately, many of these subterranean museums have been vandalized. That's why veterans of the underground are tight-lipped about their location. Host Marianne Eaton joins members of the Vermont Cavers Association in Rutland County for a trip underground to explore one of Vermont's deep treasures.
