About Sheet Rock Lighthouse

A 9-meter cylindrical fiberglass tower marks Sheet Rock, painted white with two horizontal red bands. First lit in 1980, it stands on a small island at the entrance to Sheet Harbour, Nova Scotia. The light emits a single white flash every 4 seconds, with a geographic range of 13.9 nautical miles. The focal height of the light is 23.5 meters. The current structure replaced a keeper's house built in 1936, which burned when decommissioned in 1980. The site is open to the public, but the tower is closed.

Why it matters: The lighthouse is important for navigation into Sheet Harbour, marking the channel entrance for local maritime traffic.
