Pulaski Shoals marks the northeast edge of Dry Tortugas National Park, a spread of shallow coral heads where the shoals claimed many ships before charts and navigation aids. Divers go for the big animals along the deeper reef edge: large grouper, sharks, turtles and formations of eagle rays.
Also known as Pulaski Shoal, Pulaski Reef, Pulaski Shoals Area.
Where it is and how deep
24.6933° N, 82.7733° WApproximate position — the dashed circle shows where the site lies; your operator's briefing has the mooring.
The dive
Inside the park boundary the reef is a field of scattered, very shallow coral heads. Among them lie the scattered remains of a wide variety of shipwrecks, ships these shoals claimed in the days before navigational aids and accurate charts.
For a deeper dive, divers go just beyond the boundary buoys to 23–24 m (75–80 ft) and follow that depth curve, looking for changes in reef elevation. Descending into the deep blue water, they meet very large grouper, plenty of snapper and often sharks: black tips, hammerheads, bull and nurse sharks are all common, along with turtles and large formations of eagle rays.
