Part of a new string of caches on the river. I've been wanting to place one on this island for a number of years now. Every time I drove through Constantine, I could see it there from the bridge, calling to me. This is a water cache obviously and you will need some sort of watercraft in order to reach it. Watch the poison ivy and thorns here. You are looking for a small lock and lock container tucked away in what should be a safe spot.
The name is in reference to one of my favorite old monster movies, which happens to take place on an island. Look out for them!
