The Maquoketa Caves are impressive. It was great to be in the Park all day, looking for clues. The caves didn’t seem very deep at first, but I went to the very end of the Dug Out cave, crawling, and found another bigger chamber that didn’t seem to be on any leaflet. The place was covered in bats’ guano and the stench was pretty strong so I couldn’t stay for hours but I tried to explore the area with my brand new torch and I have found a toothbrush, a comb and a pen, as well as little piles of bones and fruit stones. Marking on the walls looked like days and weeks but there were so many that it would add up to years.
