I found what looks like an old artillery shell yesterday. The area I found it in was used for target practice up until the 70's but was supposed to be cleaned since then.
What does this look like to you guys? The whole thing is about a 1 1/2 feet long and shaped like a giant bullet.
If this was an old shell could it possibly still pose a hazard? It is located in about 35ft of water in a very popular/busy snorkel and dive spot.
