Granite Island Lighthouse: Introduction

Twelve miles out from Marquette's Lower Harbor, past water that can shift from glass-calm to violent in the time it takes to regret leaving shore, a small granite outcrop rises from Lake Superior. On it sits a square-towered lighthouse built of cut stone, its white limestone trim catching whatever light the lake allows. The U.S. Lighthouse Board commissioned it in 1869, positioning it to guard the busy ore-shipping lanes that connected the iron ranges of Michigan's Upper Peninsula to the hungry furnaces downstate. For nearly seventy years, keepers climbed to tend a fourth-order Fresnel lens that threw a red flash every ninety seconds across Superior's black expanse. Then automation arrived in 1937, the keepers left, and Granite Island began its long drift toward something no one expected: a second life as a privately owned outpost of science and art.

The island is private and closed to the public, but the U.S. Coast Guard maintains an automated navigational aid on a gray steel tower separate from the historic lighthouse. Its characteristic is a white flash every six seconds, visible to vessels passing through waters that have...
