This morning dawned clear and cold, 16 when the sun came up in Keystone, SD, but it warmed up fast to about 50.
We began our day by returning to Custer State Park, a huge reserve in the Black Hills. We drove the Iron Mountain Road to the Wildlife Drive, hoping to see some wildlife. We did!
Yep, the buffalo / bison roam freely.
Leaving Custer State Park, we were on parkland for Wind Cave National Park.
Our next stop was Mammoth Site in Hot Springs, SD, a National Natural Landmark. This is an active dig and research center enclosed over the sedimented remains of a sink hole/pool. Probably because it provided water and grass on it's edges, but was rimmed with slippery rock, it became a natural trap for large animals who fell in and couldn't get out. Many, even most of these victims were mammoths.
The last stop I'll show you today is in Alliance, Nebraska - Carhenge!
