DIORAMA: Tourist Ursula Shacklock of Murfreesboro, Tenn., reads information beside a historical diorama at the Big Bone Lick State Park in Union, Ky. The display depicts the struggle of Ice Age-era animals who came to lick the salt bogs at the edge of the glaciers and got caught in the bogs. A woolly mammoth, in the foreground, is knee deep in the bog. Fossils from that era are displayed in the museum and gift shop in the background.
