An unexpected mammoth

While visiting Wisconsin's Interstate Park over the weekend (happy 80th birthday, Smokey Bear!), I was surprised to come across another resident of the Cottage Grove area at the Ice Age Center:

According to the display, this mammoth tooth was discovered on Grey Cloud Island on July 9, 1987, by Arnold Sanford of Frederic, Wisconsin. This is the kind of thing that makes me wish we had an update to Stauffer "1945". (Even if I have to do it myself.) There must be plenty of other post-WWII finds scattered across Minnesota that are only known locally. When I was a little kid, my mother told me that part of a mammoth tooth had been found in Red Wing by a Boy Scout; I've never been able to find anything about it, but it certainly wouldn't surprise me!

Incidentally, the Ice Age Center also has other fossils and cast fossils of Ice Age mammals from the area. (Interstate Park is the western terminus of the Ice Age National Scenic Trail and one of the components of Ice Age National Scientific Reserve.) The most significant are bison bones and a cast skull from the park's bison bonebed, discovered in 1936 during CCC work. The bonebed is in my hopper of topics; until then, here are the specimens on display.
