About Lake Huron Cut Lighthouse

Also known as: Lake Huron Cut (Light 7)

This lighthouse marks the entrance to a dredged channel on Lake Huron, situated about 3.75 miles north of the Fort Gratiot light. The structure consists of a 14-meter cylindrical tower with a single green horizontal band, rising from an equipment building on a concrete pier. It emits a green flash every 6 seconds, visible for over 11 nautical miles. This light now serves the channel's entrance, a duty formerly carried out by the lightship Huron. The lighthouse itself is not open to the public, but its surrounding grounds are accessible.

Why it matters: The lighthouse is essential for guiding vessels into the dredged channel connecting Lake Huron and the St. Clair River, a significant route for Great Lakes shipping.
