Rock of Ages Light, Lighthouse in Keweenaw County, Michigan, US.

Description

Rock of Ages Light is a lighthouse in Keweenaw County built from steel with a cylindrical tower and black base. The structure sits on a small rocky island in Lake Superior and operates automatically today without a resident keeper.

History

This lighthouse began operating in 1908 to warn ships away from a dangerous reef that had caused many wrecks in Lake Superior. Its construction was a direct response to repeated maritime disasters in these waters.

Culture

The original Second Order Fresnel lens from the lighthouse remains on display at the Windigo Visitor Center, demonstrating early maritime navigation technology.

Practical

The lighthouse is best viewed from ferries that travel between Grand Portage, Minnesota and Isle Royale. Binoculars help when observing from the boats since the structure sits exposed on open water.
