June 30, 2021 – Boaters on northern Michigan’s Lake Superior captured a dramatic video of a large section of cliff wall crashing into the water. The piece of the cliff wall, which consists of sandstone and dirt measuring around 200 ft., fell at Pictured Rocks National Lakeshore in Michigan’s Upper Peninsula. The rock fall looked like a quarry face coming down after a blast. “We could hear the cliff wall popping and cracking and within 60 seconds a section of cliff approximately 200 ft. wide fell before us,” Jahn Martin told WLUC-TV. “The splash and swell wave were very dramatic.”
