How to see it

Above water and inside the horizon from Marblehead Lighthouse, 20 km (13 mi) away, so on a clear day it can be seen from there, and CoastFinder puts a label on it.

On the website for now. Massachusetts's lighthouses are in the web viewer first, and they are coming to the CoastFinder app, which covers the North Carolina coast today. Follow @coastfinderapp to hear when Massachusetts arrives.

Not for navigation. Positions and depths come from public charts and records, with their sources named above; they are for looking, not for piloting a boat.
