How to see it

Above water but beyond the horizon from Key West Lighthouse, 124 km (77 mi) away: the curve of the earth hides it. CoastFinder draws it faintly and marks it hidden, with its bearing and distance.

On the website for now. Florida'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 Florida arrives.
