Ride the current in Cross Country Creek long enough, and you'll find yourself carried into a long-forgotten cave at the base of Mt. Gushmore. Here among the walls of ice and stone, you may just discover clues to the ancient history of the area around Blizzard Beach.
Petroglyphs carved in the rocks indicate that the freak snowstorm that created Blizzard Beach wasn't a one-time occurrence. It happened in the prehistoric past, too. There are primitive drawings on the walls of snowflakes and snowmen, along with mammoths and alligators on skis!
There's also a fossil record of prehistoric melting, as human figures are depicted making the transition from skis to inner tubes.
Look closely, and you may make an even more startling discovery. The petroglyphs seem to show the presence of an Abominable Snowman! Was it real or just imagined by the native population? None have been sighted in these parts in recent history, but then again... the Yeti on Expedition Everest isn't far away from here.
