Around 500 years ago or 2 million (depending on who you ask) glaciers covered this area bringing all kinds of destruction to the topography and carrying sediments locked in the ice from over a hundred miles away. These phenomena can be witnessed at Trickling Falls if you use a little imagination. Was the “Canyon” cut out by mere rainfall? I believe there was a much greater flow of water that etched out this small ravine. I can picture a giant waterfall flowing over the high edge of a massive sheet of ice. As it receded, the “Canyon” was sculpted from the flowing water eroding its way over the limestone as it froze and thawed speeding the process along. Not far away the White River runs through a wide valley and if you follow it upstream you will see that it was a drain river from a huge glacier plane to the East. And not far to the south there is evidence that the glacier reached its southern most advancement. There is also fossil embedded limestone, geodes, and other rock and stone not native to southern Indiana! The pictures presented will be updated as I get out and take better photos of Trickling Falls.
