How to see it

Above water and inside the horizon from Annisquam Harbor 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.
