Unearth the geological wonders of Idaho’s Snake River Plain, a land shaped by volcanic eruptions and mega-floods among other powerful forces of nature. Marvel at Shoshone Falls, which plummets from a height of 212 feet — 45 feet taller than Niagara Falls. Discover dramatic formations at City of Rocks National Reserve. Explore the visitor's center of the Hagerman Fossil Beds National Monument to look at fossils and replicas. Hear various explanations for the still unsolved mystery of the Hagerman horse skeletons, deposited in a single spot over 3 million years ago. Get a firsthand overview of the fossil beds and nearby areas from a site along the Oregon Trail. While on a whitewater rafting trip, learn the exciting history of the lava flows damming the river, the clays deposited in the lake, and the Bliss Landslide. Walk the lava fields of Craters of the Moon National Monument, formed by major eruptions which occurred as recently as 2000 years ago, to find lava caves, cinder cones and more. Learn how Box Canyon was formed by a mega-flood and examine other geological evidence of flooding. All of this is used to piece together the exciting geological and paleontological story of a unique landscape.
