The Mammoth Site of Hot Springs contains thousands of fossilized mammoths, and was discovered by chance in 1974 while excavating for a housing development in South Dakota. Their website offers visitors a 360-degree virtual tour of the unique museum that was built over the site of the now dry sinkhole, along with views of excavations that are still in progress. The "Paleontology" tab informs visitors not only about the woolly and Columbian mammoths that drowned in the sinkhole, but other animals as well. The "Mammoth Site Vertebrate List" link shows a slew of other animals, such as camels, shrub oxen, and the giant short-faced bear that lived throughout the Great Plains of South Dakota. A PDF of the 85 species of flora and fauna recovered at The Mammoth Site, as of January 2008, is also available in the same link. Visitors should also check out the "Research" tab to learn about current and ongoing research at the site.
