About Cherry Island Lighthouse

The Cherry Island Lighthouse, established in 1911, guides mariners at the southwest end of the island, separating Chaumont Bay from Guffin Bay. This location is about 10 km southwest of Chaumont. The current structure is a 12-meter square cylindrical skeletal tower topped with a red daymark panel. An earlier structure, described in 1913, was a 7.5-meter square pyramidal skeletal tower. The lighthouse emits a white flash every 4 seconds, with a geographic range of 11.3 nautical miles. Its focal height is 13 meters.

Why it matters: This light is important for safe passage through the channel between Chaumont Bay and Guffin Bay, assisting vessels navigating the confluence of these two water bodies.
