U.S. Naval Radio Station Otter Cliffs was a United States Navy radio receiver facility located in Acadia National Park on Mount Desert Island, south of Bar Harbor, Maine. The station was commissioned on August 28, 1917, under the command of Lt. Alessandro Fabbri, who had personally cleared the land, built and equipped the station, and offered it to the government in exchange for a commission in the Naval Reserve and assignment as Officer-in-Charge. Prior to the war, Fabbri was a licensed radio amateur with the U.S. Government issued call sign 1AJ. Otter Cliffs was the Navy's best transatlantic radio receiver site because of its absence of nearby man-made radio noise, its unobstructed ocean path from Europe, and the outstanding receivers, antennas and noise mitigation techniques developed by the Wireless Specialty Apparatus Company under the leadership of Greenleaf Whittier Pickard. Pickard is well known for his early inventions in connection with loop aerials, direction-finding systems and static mitigating devices used at Otter Cliffs during the war. His technical achievements and illustrations of equipment at Otter Cliffs during the war were documented in detail in the Proceedings of the IRE. Edmond Bruce, a Navy enlisted man, served as chief electrician for the transatlantic receiver during the war. He later became a widely recognized radio engineer and inventor. By the end of the war, more than 100 Navy enlisted men and 25 Marines were assigned to the station. By 1933, however, its buildings had become dilapidated and Navy funds were not forthcoming for repairs. When John D. Rockefeller Jr. suggested that it be removed, the Navy agreed to include the station in his donation to Acadia National Park, provided that he would build an equally good receiving station nearby. He did so at the tip of the Schoodic Peninsula, about five miles away across Frenchman Bay, and Feb. 28, 1935 Otter Cliffs was decommissioned and the new Winter Harbor station was commissioned. (It later became Naval Security Group Activity, Winter Harbor, and on July 1, 2002, was decommissioned and transferred to the National Park Service.)

Acadia National Park
Acadia National Park

Acadia National Park is an American national park located along the mid-section of the Maine coast, southwest of Bar Harbor. The park includes about half of Mount Desert Island, part of the Isle au Haut, the tip of the Schoodic Peninsula, and portions of sixteen smaller outlying islands. The park contains the tallest mountain on the Atlantic Coast of the United States (Cadillac Mountain), exposed granite domes, glacial erratics, U-shaped valleys, and cobble beaches. Its mountains, lakes, streams, wetlands, forests, meadows, and coastlines contribute to a diversity of plants and animals. Woven into this landscape is a historic carriage road system financed by John D. Rockefeller Jr. In total, it encompasses 49,075 acres (19,860 ha; 76.680 sq mi; 198.60 km2) as of 2017. Acadia has a rich human history, dating back more than 10,000 years ago with the Wabanaki people. The 17th century brought fur traders and other European explorers, while the 19th century saw an influx of summer visitors, then wealthy families. Many conservation-minded citizens, among them George B. Dorr (the "Father of Acadia National Park"), worked to establish this first U.S. national park east of the Mississippi River and the only one in the Northeastern United States. Acadia was initially designated Sieur de Monts National Monument by proclamation of President Woodrow Wilson in 1916, then renamed and redesignated Lafayette National Park in 1919. The park was renamed Acadia National Park in 1929. Recreational activities from spring through autumn include car and bus touring along the Park Loop Road; hiking, bicycling, and horseback riding on carriage roads (motor vehicles are prohibited); fishing; rock climbing; kayaking and canoeing on lakes and ponds; swimming at Sand Beach and Echo Lake; sea kayaking and guided boat tours on the ocean; and various ranger-led programs. Winter activities include cross-country skiing, snowshoeing, snowmobiling, and ice fishing. Two campgrounds are located on Mount Desert Island, another campground is on the Schoodic Peninsula, and five lean-to sites are on Isle au Haut. The main visitor center is at Hulls Cove, northwest of Bar Harbor. Park visitation has been steadily increasing in Acadia over the past decade, with 2021 seeing a record count of 4.07 million visitors.
