| East Quoddy Lighthouse, Campobello Island, New Brunswick, Canada © Doug Hickok If you ever wanted to know what a lighthouse foghorn (diaphone) looks like, this is it. Even though it is pointed toward the ground, the sound it makes is loud and carries long distances. It operates by forcing compressed air through an apparatus, making extremely powerful low frequency notes. So don't stand next to one when it is blowing. This one, by the way, was quiet. East Quoddy Lighthouse is one of the oldest in Canada. Although it is unmanned, it serves an important function in warning fishing vessels of the treacherous rocks at the tip of Campobello Island. And it is especially useful for guiding boats through the dense Bay of Fundy fogs. |
