Local divers Pete Lindquist, Chuck Nebel, Tom Bathey, and John Stillman recovered a large anchor buried in the sand of Munising Bay in 1980. Estimated to weigh over 1500 pounds, the anchor may have been lost by the barque Chenango on November 20, 1875, when she ran aground on Grand Island reef and then sank. The Chenango was a 150 foot schooner carrying 500 tons of iron ore from Marquette to the village of Onota, now Christmas. Her remains now lie in 10 feet of water a few hundred yards south of Wood Island. In 1988, the Department of Natural Resources declared 131 square miles of Lake Superior near Munising an Underwater Preserve, the first established in Michigan. Laws protect the remains of shipwrecks and other natural resources there, and removing any artifact from the preserve is illegal. The Alger Underwater Preserve is one of the most popular scuba diving areas in the Great Lakes, with attractions including sea caves, intact shipwrecks, and underwater interpretive trails.
