Mammoth graveyard

Accidentally discovered in 1974, this site in Hot Springs, South Dakota is the largest repository of Columbian mammoths in North America. To date 60 complete mammoth skeletons have been dug up. It all started some 26,000 years ago when a male mammoth slipped into a sinkhole to perish in the bottom. The tragedy was repeated several times over the years and before the pond filled in at least 100 elephants had died.
