Ross Island Lighthouse

Ross Island lighthouse in the fog, built in 1878 on Grand Manan, New Brunswick, Canada. You can walk to the island at low tide but for a short time either side of the low tide before the tide returns quite quickly, and the path is dangerous if it's under water. Therefore time is of great importance so as not to get trapped on the island.
Location: Grand Manan, New Brunswick, Canada.
