Lewis & Clark Caverns State Park is located in the London Hills, a relatively young geological setting. But the upheaval of these rocks exposed tales of the past that dates back over a billion years. Discover stories of mountains thrusted up from flat plains, inland seas teeming with life, and volcanoes blanketing everything in thick ash. Unveil secrets previously buried deep underground and understand why geologists far and wide come to study the rocks of the park. Park employee (and AmeriCorp member) Tamara Beal will offer her insights and photos in this informative presentation.
