Light Hearted ep 72 – Sean Todd, Mount Desert Rock, Maine

More than 20 miles from the nearest port at Mount Desert Island in Maine, low-lying, wave-swept Mount Desert Rock is only about 17 feet above sea level at its highest point. Congress appropriated $5,000 for a lighthouse on Mount Desert Rock on March 2, 1829, to aid mariners heading to Frenchman and Blue Hill Bays from the south. The light went into operation on August 25, 1830. The structure weathered many storms before being replaced by a new 58-foot granite tower in 1847. The new tower was designed by the noted architect Alexander Parris.

The station was automated in late 1977. The light station was then leased to Bar Harbor’s College of the Atlantic for use as a whale watching station. Under the Maine Lights Program, Mount Desert Rock Light Station, along with Great Duck Island Light Station, became the property of the College of the Atlantic in 1998. Allied Whale is the marine mammal research division of College of the Atlantic.

    1. From what I’ve heard, whales are not seen much near there anymore. Sean Todd talks about that in this interview. They were much more common around there several years ago. But it’s very possible you could see something.
