For some time, the wreck site of the USS Macon has been explored in a limited fashion. Earlier this year, the wreck site (the exact location is not publicly known at this time) had been included on the National Record of Historic Places. The wreck is also considered a U.S. Navy grave site.
The wreck of the Macon's sister ship, the Akron has not yet been located.
Until next time,
The USS Marcon is in one of my Indiana Jones' books.
Thanks for the news!
