Tettegouche Arch Falls into Lake Superior

The scenic Tettegouche stone arch on Lake Superior’s North Shore collapsed into the lake in recent days. The arch was a popular feature of Tettegouche State Park.

The Duluth News Tribune has the story, HERE, as well as before and after photos of the arch.

Tettegouche park specialist Jim Bischoff said initial reports of the collapse came Saturday, although it’s unclear when the rock bridge, a popular subject for photos, fell into the lake.

No particular human or natural event caused the arch to collapse, according to Bischoff.
