Tettegouche arch falls into Lake Superior

The much-photographed arch at Tettegouche State Park carved out of the North Shore by thousands of years of Lake Superior waves has collapsed.

Jim Bischoff, park specialist, said the first reports of the collapse came Saturday, but that it’s not exactly clear when the rock bridge fell into the lake.

“Definitely within the last week, but probably in the last couple of days or we would have heard about it sooner, considering how well photographed that site is,” Bischoff told the News Tribune on Sunday.

Bischoff said it appears there was no event or human activity that caused the collapse.

“There was no big wind or waves or storm. I think it was just time for it to go after how many hundreds or thousands of years,” Bischoff said. “That’s just geologic progression. We had an arch, now we have a sentinel” pillar of rock on the shore.

Tettegouche State Park is along the North Shore near Illgen City, about 30 miles east of Two Harbors.

It’s the second famous Northland waterfront arch to collapse this year. In April, officials at Apostle Islands National Lakeshore discovered that a famous stone arch on Oak Island had collapsed over the winter.
