Coastline Introduction
Why Northern Coast Lighthouses Mattered
Along the northern coast, lighthouse beams gave ships fixed bearings through fog and winter squalls, reduced wreck risk at river mouths, and helped small harbor settlements stay linked to trade, mail, and seasonal fishing routes.
-
Navigation
Fixed lantern intervals let captains distinguish headlands before modern radio beacons were available.
-
Weather
Storm logs from keepers formed one of the earliest continuous local records of wind, tide, and ice movement.
-
Settlement
Reliable coastal lighting encouraged pier building, year-round resupply stops, and steadier growth in remote shoreline towns.
