outer island light Apostle Islands Lake Superior

Outer Island light located on the northern tip of Outer Island part of the Apostle Island National Lakeshore. More historical details here.

The tower and keepers quarters are constructed of brick in an Italianate architectural style completed in 1874. Originally equipped with a third order Fresnel lens made of six bulls-eyes revolving once every nine minutes creating a flash every 90 seconds. This lens has since been replaced with an LED source. The lantern stands 86 ft above grade but is on a bluff so the focal plane is 130 ft above the lake.

A tram system descends to a concrete landing on the lakeshore enabling equipment and supplies to be off-loaded and moved up the bluff. Restoration work is underway on the buildings and bluff to preserve this national historic landmark site.
