In this video, I do a little treasure hunting on Florida's legendary Treasure Coast, from the Seagrape Beach access all the way to Wabasso Beach. This general area is the site of the 'Green Cabin wreck' (the San Martin), a Honduran ship that sank in 1618. The 'Corrigan's Wreck' site (1715) lies just several hundred yards to the south. In this video, I find a small ship spike (nail).
