Small Hard Plastic Cylinder Cache

Another long name but appropriate, the Small Hard Plastic Cylinder Cache , not sure why such a tough container was needed for just a log, but maybe it was the location. I found this on the Rhode Island coast, aside of an abandoned military bunker, maybe they found this container in there, it looks old. The metal scrap threaded in the hole on the screw off lid came in handy, I would have needed a pliers otherwise.
