West Sister Island Wilderness

When sailing ships first navigated the waters of Lake Erie, a lighthouse perched on the westernmost point of West Sister Island guided them. Keepers operated the light until 1937 when it became automated. The lighthouse and the surrounding area now form the West Sister Island Wilderness in the West Sister Island National Wildlife Refuge, managed as a satellite of Ottawa National Wildlife Refuge. This island Wilderness rises from the water to a not-very-high point of 35 feet. More than 75 percent of the land is shaded by a 40 to 50-foot-tall hackberry trees.
