LOESS HILLS of the Lower Mississippi Valley

In fact, not only have mastodon remains been found around Natchez, but also remains of ancient ground sloths, a form of native horse that was a big, hulking, draft-horse-like creature, and many other extinct, Ice-Age animals. ... Also curious is that the remains of these large animals have always been buried deep inside or below the loess, not atop it... Yes, something curious -- quite possibly even something majestic in scope -- has been going on here. This long bluff at Natchez and all along the western boundary of the Loess Hills has a story to tell...http://www.backyardnature.net/loess/curious.htm
