MUNISING, Mich. – Boaters along the Pictured Rocks shore in Lake Superior heard rumblings, then looked up to see a 200-foot cliff breaking off. One of the boaters, John Martin, happened to be shooting video of the picturesque shore and caught it all – while also yelling to his companions to put their pontoon boat in reverse. The whole thing lasted about 60 seconds, Martin told Marquette television station WLUK. The pontoon boat rocked from the super splash but stabilized No one was hurt.
Horrifying splash down. Pictured Rocks National Lakeshore park, in the Michigan Upper Peninsula, is known for changing colors when groundwater seeps through the cracks. Sometime the seams crack the rocks apart.
