D. Graham Copeland graduated from the Naval Academy and was later hired as an engineer by Barron Collier to help build the Tamiami Trail. He was one of the first county commissioners of Collier County. He made a map of Collier County in 1947, and it is one of the best that I have ever seen. He went out and located 10 sites related to the Third Seminole War, fort sites and villages. His accuracy was very good--if you learn how to land a ship in port after crossing over 3,000 miles, then you have to be good at surveying.
James Hammond went out and found 9 of the 10 markers that Copeland had erected. One no longer exists--destroyed with the building of Ava Marie. None of these markers are public knowledge, but I will mention them in the next few weeks. Here is the first one.
Monument at the site of Fort Shackleford, at Big Cypress Seminole Indian Reservation.
This is all you will ever see of it, because you can't visit it. Copeland's marker still exists on top.
Hammond's book details all these Seminole War sites, the towns that no longer exist along the trail and highway 29, and the mystery of Deep Lake.
