The landmarks have all changed, so you will have to find somebody who knows how to find'em today, but:
Whiskey Wreak: several miles west from where the main road comes down to the water at Gulf Shores. Used to be a wiggle in the road near the wreak. Civil War blockade runner, boiler and machinery exposed, hull outline sometimes, big bronse nails in the hull, about 100 ft long, less than 100 yards from shore.
steel sailing vessel, west of where the main road meets the beach, but not far,200+ ft long, nice stern, more than 100 yards from shore. Given passage of several hurricanes, this one might be gone.
Jetty at Alabama Point is excellent for flounder at night and huge specs at dawn. Not sure what the rules are, might be illegal today.
Good luck searching.
