Operation Lighthouse Rescue Preview

On the picturesque bluffs at the very tip of the island of Martha’s Vineyard, disaster looms. The historic Gay Head Lighthouse is soon to become the next victim of the persistent erosion of the island’s cliffs. Built in 1856, the more than 400-ton structure soars 175 feet above the sea. But over the years, storms and the raging ocean have eroded the headland away.
