The Grand Island Harbor Rear Range Light is a lighthouse located off M-28 near Christmas, Michigan. It is also known as the Bay Furnace Rear Range Light. The corresponding front range light was replaced in 1968; the rear range light was listed on the National Register of Historic Places in 1990.[8] It is no longer an active aid to navigation.
The grounds only are publicly accessible, but a hike is required.[9]
History
The Grand Island Range Lights were lit first in 1868.[1] The original front range light was a wooden pyramid that held a sixth order Fresnel lens.[1] The original rear range light was a sixth order Fresnel lens in a wooden tower atop a frame keeper's house,[4] 500 feet to the rear of the front range light.[1]
By 1914, these original frame structures were severely rotted, and both were replaced[1] as part of a broader effort of replacing nearly all harbor lights with steel-framed structures.[2] The new front range light was a 23-foot tall iron mast.[1] 750 feet (230 m) to the rear of the front range light, a new automated[2] rear range light was installed.[1] The new rear range light was a 64-foot tower, the upper half (painted white)[10] of which was part of a tower originally located at the Vidal Shoals.[1] near Sault Ste. Marie.[10][11] In 1939, the sixth order Fresnel lenses were replaced with 350 millimeter glass lenses, which still used acetylene gas.[4] In 1968, the front range light was replaced with a "D9" style tubular steel structure;[4] in 1969 the lights were deactivated.[2]
Rear range light description
The 1914 Rear Range Light is a steel conical tower, 64 feet high, with a round lantern.[2] The light of one of the tallest, if not the tallest, of the riveted steel plate light towers installed around the Great Lakes.[2][12] The tower sits on a concrete foundation; a metal door in the base of the tower and interior spiral stair provides access to the light.The tower painted black on the bottom and white on the top, with a black lantern room. The existing light was built in 1914 replacing the original 1868 station.[2][13]
