Otter Island Light

 A Canadian light located on the northwest tip of Otter Island in northeast Lake Superior. The small island is part of Pukaskwa National Park. Marathon, Ontario is the closest town.

In 1975, the keeper at this remote station watched the ill-fated freighter Edmund Fitzgerald pass by in a storm.

This lighthouse is very isolated and accessible only by boat. A 21-foot, an octagonal white concrete structure topped by a red lantern, the light has a focal plane of 97 feet above the lake. Established in 1903, the light is displayed flashing white every 8 seconds and is visible from a distance of 18 miles.

The keepers dwelling is a two-story white clapboard structure with a red roof and red trim. An assistant keepers dwelling is a single story with a similar paint scheme, as is the boathouse near the shoreline. A modern looking steel-sided generator building completes the island station.

Otter Island and nearby shores provide vital shelter and habitat for a small, at-risk herd of woodland caribou. Caribou are sensitive to disturbance and human presence may cause them to move from their preferred habitats or may attract predators to the area. To help protect this important habitat for caribou, access beyond the lighthouse and keepers dwelling is prohibited year-round. The former light keepers on Otter Island are open to the public for emergency use only. Visitors are encouraged to enjoy the island from the water.
