1964 Map of Round Island

USGS Topo · Published 1978

About this map

Mackinac Island and its storied fortifications anchor this 1964 survey of the Straits of Mackinac. The map details the cluster of 19th-century sites on the island's southern tip, including Fort Mackinac and Fort Holmes, along with geological landmarks like Sugar Loaf Rock and Skull Cave. Most of the island is preserved within Mackinac Island State Park, while a Ferry line connects the settlement to the mainland across the open water.
