The Mammoth Site


Ice Age mammoths and other creatures, in search of water fed by ancient hot springs, fell to their deaths in a sinkhole on this site. The sediment that later filled it preserved their remains, which were discovered in the 1970s. In addition to Columbian and woolly mammoths (ancestors of the elephant), the site contains precursors of the bear, camel, llama, wolf, and other species. The museum offers exhibits and a 30-minute guided tour during which you’ll see fossilized skeletons still embedded in the ground.
