Cape Hatteras Lighthouse Engineering Marvel Stands Tall Against Coastal Erosion
Cape Hatteras Lighthouse Engineering Marvel Stands Tall Against Coastal Erosion - 1870 Construction 1,500 Feet from Ocean
When erected in 1870, the Cape Hatteras Lighthouse stood a seemingly safe 1,500 feet from the Atlantic Ocean. This initial distance, though, proved to be a deceptive measure of the enduring threat posed by coastal erosion. The ocean steadily encroached upon the lighthouse's location, gradually shrinking the buffer zone. The early 1900s saw a sharp increase in the rate of erosion, with the ocean's edge closing in on the landmark. By the mid-1930s, the lighthouse was a mere 100 feet from the constantly shifting shoreline, a dangerously close proximity that highlighted the building's vulnerability. Facing this precarious situation, the Coast Guard eventually chose to abandon the site in 1936. The National Park Service, recognizing the historical and engineering significance of the lighthouse, took on the responsibility of safeguarding its future.
