With my friends joining me, I have claimed an island in the middle of the Arkansas river as my own and renamed it “Mojo Island.” After verifying GPS coordinates, I placed a container full of treasure and a log for those intrepid explorers who follow me. From the geocache description:
This geocache is rated as a  5/5. Not everyone may be able to attempt this cache. It will require walking down rocks, wading, or possibly swimming in river water currents (not suggested) You may have to use a canoe or kayak to access Mojo’s island. Either way, you need to understand that you assume the risk. Myself, nor Geocaching.com/Groundspeak can be held responsible for your decision to attempt to retrieve this cache. You are looking for a container on the island itself. It could have a tendency to leak, especially in high water, so if you cannot sign it then a photo of you and the container will qualify as a smiley in your log. Due to the nature of the terrain and difficulty level, photographic proof is required in addition to the signing of the log. Please send images to me directly instead of in the geocache log. Good luck and stay safe out there as there are potentially sharp rocks along the shorelines.Â

I’ll be headed back to Mojo island as soon as I have found a more suitable container, more treasure to add to it and even a human skeleton that I will chain to a tree as a waypoint for future explorers to discover.
