Are you sure CYOA? I think you're referring to the The Theovald Eric Moorehead Dock and Terminal at Enighed Pond, St. John. That's where the car barge berths.

The Creek is where the destroyed C&I office, and NPS docks are located. At the head of the Creek is the wharf where the St John passenger ferries to Redhook and BVI depart from. I'm assuming that CBP setup a temporary building there.
