Split Rock Lighthouse
An intact 1910 lighthouse, keeper’s home, fog-signal building, and Lake Superior cliff explain navigation, isolation, labor, and the violence of November weather.
Artwork inspired by Birney Quick
Split Rock was built after the 1905 Mataafa Storm wrecked or damaged ships along the North Shore. The tower’s Fresnel lens, fog signal, oil storage, and keeper routines reveal a system designed to make a remote iron-ore route safer before electronic navigation.
The famous postcard view comes from below, but the historic site sits high above the shore. Tour the station first, then descend only if conditions and mobility allow; wind, ice, stairs, and steep trails can turn a short scenic stop into a serious outing.
