UFO Sighting in Makanda, Illinois on March 27th 2016 – Snapped 5 pics and this was the middle pic. Noticed 3 hours later upon review

Went to Giant City State Park to hike and relax. Decided to take some pics Underneath almost dry waterfall at Devil's Table formation and snapped 5 pics while clouds were coming in before a storm scheduled to hit in a couple hours. I was really focusing on clear pics of water coming off of cliff above. I DID NOT NOTICE object until I got home about 2 hours later what was in the pics.
