On vacation in the Black Hills area this past week, we spent a few hours at Mammoth Site in Hot Springs, SD.
A sink hole formed about 26,000 years ago. It filled with water. Thirsty animals fell in and couldn't get out. With time, this filled in and was preserved.
When a plan for land development scratched the surface in 1974, its value was quickly realized!
As we toured the rim of the excavation an international group of folks from Earthwatch was . . . carefully . . . slowly . . . working to uncover bones . . . all within a beautiful building. Pretty impressive.
Here's more information about the volunteer group working at the site during July.

The fossil bones of Columbian and woolly mammoths
are found scattered throughout the sinkhole. Snails were discovered at the edge!

My mom was one of the EarthWatch volunteers in the first year or two they dug at this site! I love that snails have been found! Vicky
