It all started when I visited Happy Hollow Park, a few minutes drive from Purdue. Wow, this place was impressive (considering it's location in Indiana). The first thing I noticed was the creek bed. What could have possibly formed this other than a cave/spring? I searched the entire place for springs. I followed every single source of water to the top of the valley. Almost every source was being supplied by culverts!(drainage piping) This is not what I wanted to find. HOWEVER they WERE human sized! AND there was airflow! Now what turns me on more than airflow? Mainly, women, along with deep pits, big borehole and beautiful women. Airflow always means there is more passage! I called Ryan and Erik and informed them I found a "cave" at Purdue. They didn't believe me and with good reason. Late one night, we all found ourselves sneaking into one of these "sewer" caves. I was actually impressed with the formations in there. There were neat flowstone formations and very impressive rim stone dams, hundreds of them. Now, these are not natural formations. Cave formations are thought to take thousands of years to "grow" one single inch. I suggest that they grow fairly rapidly and then stop once all the minerals in the rock have been used up. Either way, damaging them won't allow them to growback anytime soon.



All caves exist in the lower 1/3rd section of Indiana. Why? Because all of the northern 2/3rds section of Indiana is covered in glacier till. This is why it's so flat. Although it sucks in ways, it makes very good farmland and aquifer system for drinking water. Believe it or not, northern Indiana actually used to look like southern Indiana before the glaciers filled all the valleys and ridges.



So, everyone thought I was crazy for trying to find caves way way way up here. They thought I had officially lost it! And exploring the sewers didn't help! Glacier till is mainly like dirt and that's what the entire 2/3rds of Indiana consist of on the surface. There is bedrock, but it's buried way deep (the pre-glacier landscape). So how could there be caves without bedrock (rock)? The key is the Wabash River.
