On May 18, 1986, a 130 foot US Army dredge, the Corey N Chris, was sunk in 260 feet of water as part of the Broward County artificial reef program. Then, on May 15, 1988, a 226 foot freighter, the Ronald B. Johnson, was sunk as part of the same program. The R.B.J. landed, by accident, right on top of the Corey N Chris perpendicular to it. Today, these wrecks sit upright in 260 feet of water.
