I first found this area on one of my many long walks through Lafayette, IN. After living there for 8 years and shooting well over 20,000 photos around town I was having to walk farther and farther to find anything that I hadn't seen yet. I thought I'd made it to all of the interesting locations when I accidently wandered into this system of creeks and tunnels leading under natural ridges, railroad tracks, and eventually to the wastewater treatment plant's general area.
It was great to see something new, and although all of the tunnels here were fairly short, it rekindled my interest in draining and exploring abandonments. The map above provides a good overview of the area. The building to the left of the map is the Lafayette wastewater treatment facility. The closed road I followed is visible traveling through the woods. To the south it joins with a split in the railroad tracks and may be used as an access road for repair on the signals in that area.
I was excited to see the drains, but even more so to catch a glimpse of that waterfall through the tunnel. The photos on this page were from a day in March and the water was insanely cold... it actually snowed on my walk home. This just made the waterfall grow in my mind until it was some kind of monstrosity of a hidden national treasure that had been forgotten for years. I didn't get a chance to go back until I dragged two friends (and two more who randomly spotted us on the road and came with) along for a trip a month later.
The pictures speak for themselves on this one.
I also speak for the pictures.
