THE WABASH TORRENT
Glaciers advanced into Indiana throughout the Ice Age. As the glaciers retreated, large amounts of water were trapped by a moraine near Ft. Wayne, Indiana. The resulting lake (glacial Lake Maumee) breached the moraine about 14,000 years ago. A massive amount of water roared down the Wabash and rushed through the Prophetstown State Park area. Up to 50 feet of water covered most, if not all, of the park. Many geologists believe that this catastrophic flood - the Wabash Torrent - formed the streamlined landscape of Prophetstown State Park that we see today.
Terraces are remnants of older floodplains. Three terraces have been identified at Prophetstown State Park. To claim a find on this earthcache, please e-mail us the answers to the following questions.
1. What are the three terraces found at Prophetstown State Park?
2. As you stand on the overlook at the listed co-ordinates, which terrace do you think you are standing on?
