Marking the entrance to the fishing port of Bass Harbor, on Mount Desert Island, the Bass Harbor Head Light has been functional since 1858. Technology has changed greatly, but the new LED lights flash the same brilliant red pattern through the same fourth-order Fresnel Lens installed in 1902, 120 years before this photograph, when the light came from red-glass-covered oil lamp. This facility has guided mariners through fog and darkness toward the harbor, and away from treacherous rocks common to the rugged Maine coastline. Atlantic waves bash against the hard, Devonian/Silurian granites and basalt intrusions upon which the lighthouse stands, and may threaten it in a few million years.
