Separated by 1,000 feet, the range lights were located on the western shore of Presque Isle Harbor. Mariners were instructed that when approaching the harbor they should bring the two lights in range, one above the other, and continue on that line to safe anchorage. Aligning one’s vessel with a pair of range lights is akin to aligning the sites of a gun on a target.
The front light was displayed from a twenty-one-foot-tall wooden tower that was painted white and stood near the shore. The bottom half of the tower is square, but the corners of the upper half are beveled to create an octagon. A lens lantern originally displayed a fixed white light through a seaward facing window, just below the tower’s roofline.
The rear light shone from a tower mounted atop the pitched roof of a one-and-a-half-story, five-room keeper’s dwelling and had a focal plane of thirty-six feet above the harbor, twice that of the front light. The range lights were similar in form to those deployed at Copper Harbor and Eagle Harbor on Michigan’s Keweenaw Peninsula, and at Baileys Harbor in Wisconsin.
Keeper Isaac Codington served until his death in 1875, whereupon Captain William Sims was placed in charge of the lights. Born in Ireland in 1835, Sims immigrated to the United States while young and later sailed on the Great Lakes, eventually becoming a captain. Legend has it that Sims’ wife Adeline overhead the proceedings of a Masonic meeting held at the lighthouse, and to keep her quiet, she was made a Mason. Adeline passed away in 1881 and was buried along the range line. Her gravestone, marked with the masonic square and compass, is adjacent to Presque Isle Range Light Park, where the restored front range tower now stands. It is claimed that Adeline is the only female Mason ever, but this is quickly disproved by a little research.
On September 20, 1926, the characteristic of the front light was changed to a white flash every second, while the rear light, which remained fixed white, was mounted atop a black, pyramidal, skeletal tower at a height of thirty-three feet above the ground. In 1940, the lights were electrified and changed to fixed green, the characteristic they have today.
When old Presque Isle Lighthouse was discontinued in 1871, Keeper Patrick Garrity moved a mile north to take charge of new Presque Isle Lighthouse. At that time, Patrick and his wife Mary had five children, John, Mary, Thomas, Katharine, and Patrick. Anna, a sixth child, was born at the new lighthouse shortly after the family’s move. All of the male Garrity children plus Anna, would spend a good portion of their adult lives as lighthouse keepers on the Great Lakes. John Garrity served as an assistant keeper of new Presque Isle Lighthouse and as head keeper at Rock of Ages and Devils Island on Lake Superior. Patrick Garrity also served as an assistant keeper at new Presque Isle Lighthouse and then as keeper at Middle Island Lighthouse and St. Clair Flats Range Lights.
After having served as assistant keeper at new Presque Island Lighthouse under his father, Thomas Garrity was appointed the third head keeper of Presque Isle Harbor Range Lights in 1887. After four years, Thomas swapped assignments with his father, and Patrick Garrity, Sr. became keeper of the harbor range lights in 1891 at the age of seventy-two. Anna took charge of the lights after her father passed away in March 1903 and had her mother remain with her at the station. Anna, who never married, cared for the lights until 1927.
The front range light was replaced by a modern tower in 1967 and subsequently relocated to the beginning of the road that leads to the old Presque Isle Lighthouse. Presque Isle Township acquired the front tower in 1995 using private donations and state funds. The wooden tower was later moved to Presque Isle Harbor Range Light Park, situated alongside East Grand Lake Road and not far from the current front range light. The park includes picnic tables, restroom facilities, a sandy beach, and a swimming area. The Robert Burseky family restored the front tower in 2004.
In 1964, a mallard duck, which the family named Charlie, took up residence in a pond behind the lighthouse. Charlie became somewhat of a tourist attraction after he started chasing the Spencers’ Cocker Spaniel, nipping at his ears and often jumping on his back for a ride around the yard. The lighthouse remained in the Spencer family until it was sold sometime after 1995.
On August 31, 2013, a sculpture of Anna Garrity, one of twenty-seven women to serve as lighthouse keepers in Michigan, was dedicated at Presque Isle Harbor Range Light Park. The sculpture was crafted by Dawn Barr of Cheboygan, who earlier made a life-size sculpture of Patrick Garrity, Sr. that stands at old Presque Isle Lighthouse. Barr spent roughly 250 hours shaping, molding, and welding large pieces of steel over an eight-month period to create the sculpture as a tribute to the longest serving keeper of Presque Isle Harbor Range Lights.
