Holmes Township, Mackinac County, Michigan

Skull Cave is a small and shallow cave on the central heights of Mackinac Island in Michigan, United States. The cave was carved during the Algonquin post-glacial period by the waters of Lake Algonquin, a swollen meltwater ancestor of today's Lake Huron.Skull Cave is primarily of interest for its historical associations. It is believed to have been used as an inhumation site by Native Americans of the Straits of Mackinac area in the 18th century.While in active use as a site for human remains, the cave was also used as a refuge in 1763 by fur trader Alexander Henry, a survivor of the capture of Fort Michilimackinac by Native Americans during Pontiac's War. In his "Memoirs," Henry recalled a night spent as a refugee in the bone-strewn cavern.Henry recalled his ordeal as follows: On going into the cave, of which the entrance was nearly ten feet wide, I found the further end to be rounded in its shape, like that of an oven, but with a further aperture, too small, however, to be explored. After thus looking around me, I broke small branches from the trees and spread them for a bed, then wrapped myself in my blanket and slept till day-break. On awaking, I felt myself incommoded by some object upon which I lay, and, removing it, found it to be a bone. This I supposed to be that of a deer, or some other animal, and what might very naturally be looked for in the place in which I was; but when daylight visited my chamber I discovered, with some feelings of horror, that I was lying on nothing less than a heap of human bones and skulls, which covered the floor! Skull Cave is contained within Mackinac Island State Park. It is located 0.4 miles (0.6 km) north of Fort Mackinac in the island's interior. It was designated as a Michigan Historic Site on January 12, 1959, and granted state historical marker #L0004.

The Battle of Mackinac Island (pronounced Mackinaw) was a British victory in the War of 1812. Before the war, Fort Mackinac had been an important American trading post in the straits between Lake Michigan and Lake Huron. It was important for its influence and control over the Native American tribes in the area, which was sometimes referred to in historical documents as "Michilimackinac". A scratch British, Canadian and Native American force had captured the island in the early days of the war. An American expedition was mounted in 1814 to recover the island. The American force advertised its presence by attempting to attack British outposts elsewhere on Lake Huron and Georgian Bay, so when they eventually landed on Mackinac Island, the garrison was prepared to meet them. As the Americans advanced on the fort from the north, they were ambushed by Native Americans, and forced to re-embark with heavy casualties.

Fort Holmes is a fortified earthen redoubt located on the highest point of Mackinac Island. Originally built in 1814 by British forces during the War of 1812, the redoubt was improved by that army throughout the course of the war (1812–1814) to help defend the adjacent Fort Mackinac from a possible attack by the U.S. Army.The British named the redoubt Fort George and reinforced it with cannon, a blockhouse, and a magazine for gunpowder and other munitions. However, Fort Holmes never functioned as an independent military fortification. It was always a dependent outpost of nearby Fort Mackinac.When United States armed forces reoccupied Mackinac Island in 1815 under the terms of the Treaty of Ghent, they took possession of Fort George. They surveyed and measured their prize, which they renamed Fort Holmes in honor of Major Andrew Holmes, a casualty in the 1814 Battle of Mackinac Island. However, the American army soon abandoned Fort Holmes. The earthworks and buildings of the former redoubt slowly eroded and disappeared over the course of more than a century.In 1936, as part of its mission to provide employment through public works projects during the nationwide Great Depression, the Works Progress Administration used the original 1817 American survey to rebuild Fort Holmes to its War of 1812 appearance. As of 1984, however, most of the reconstructed buildings of Fort Holmes had again disappeared, except for the redoubt's earthen walls.In 2015 the Mackinac Island State Park completed a second reconstruction of Fort Holmes that resumes the appearance that the redoubt had in 1817. The blockhouse includes interpretive panels inside, and is open in the summer. Many visitors come to the fort site for a view of the Straits of Mackinac, much of which is visible from this lookout point approximately 320 feet (98 m) above the surface of Lake Huron and 890 feet (271 m) above sea level. The redoubt and blockhouse can be rented for special occasions.

Fort Mackinac ( MAK-ə-naw) is a former British and American military outpost garrisoned from the late 18th century to the late 19th century in the city of Mackinac Island, Michigan, on Mackinac Island. The British built the fort during the American Revolutionary War to control the strategic Straits of Mackinac between Lake Michigan and Lake Huron, and by extension the fur trade on the Great Lakes. The British did not relinquish the fort until thirteen years after the end of the American Revolutionary War. Fort Mackinac later became the scene of two strategic battles for control of the Great Lakes during the War of 1812. During most of the 19th century, it served as an outpost of the United States Army. Closed in 1895, the fort has been adapted as a museum on the grounds of Mackinac Island State Park.
