2013 - Bart Finds 8000th Geocache

A few years back I was perusing the Wisconsin Geocaching Association forums and read a discussion about favorite geocaches in the state. The one that stood out the most to me was Twin Bluffs Cave (GCXWPM) by Shrek and Fiona. I knew at that moment that the geocache would have to go on my short list of caches to complete. Unfortunately, being on the short list does not equate to pursuing the cache in a timely manner.. the cache remained unfound.

I had been planning for quite some time to find a special geocache for the milestone of my 8000th find, which I estimated to happen late December. With Twin Bluffs Cave still in the back of my mind, I knew this had to be the one. It was now or never. After some logistical planning, a three hour drive to Lyndon Station, WI, I finally made the find along with daughter Laura, Doublemoose, and his daughter Geohockey,

The most impressive thing about this adventure was not the geocache, but the impressive nature of the geological feature hiding here up in the bluffs. As you approach the cave entrance, it looks like nothing more than a narrow fissure in the side of the cliff face. But as you explore more, you soon discover that this is the entrance to a fairly expansive system of caves. At the inner room of the cave, I would estimate the ceiling to be nearly 30' high, expansive enough to hold a small disco party. The primary cave easily goes back 80 to 100 feet or more. Off the inner room of the cave, there are two caves headed in each direction normal (perpendicular) to the primary cave.

One thing that was clear to me was how similar this system is to the littoral caves on Byllesby Lake in Cannon Falls, MN. I suspect the wave and current action from melt water following the last glaciation period is what created this system, where each cave is caused by the erosion of fissures within the layers of sandstone.
