A cliff wall broke away at a national park along Lake Superior in northern Michigan, stunning some boaters who captured it on video.

They just don't make things like they use to

I often remind people sitting on or standing on a cliff edge that the edge wasn't always where it is right now. Most of them look at me like I'm speaking Martian. Ok, have it your way.

I wonder if screaming back up repeatedly helped the situation, I think so.

Everyone talking about the screaming guy in a negative light. I however, am glad he was there. He added excitement to the whole thing.

Dang, when I went kayaking to the caves a few years ago I was thinking this very if that cliff/wall broke off”
We went in a crevasse that had a Boulder hanging in it above us, it was so narrow you didn’t use your paddle, you pushed with your hands on the walls beside was I thinking ??🙄
Beautiful but could be deadly 😗

Those are sedimentary rock cliffs. Sediments don't form cliffs, which means that this has been happening for millennia. What's rare is getting it on video.

I kayaked that stretch of the shoreline a few years back. It was beautiful. Had an amazing time. So glad the cliff face held together cause in some cases we got pretty close.

This is one of the most beautiful spots in the world. Miles and miles of gorgeous cliffs along a pristine, fresh water lake.

Mosquito beach🦟 Sounds like a lovely place 😱

That entire cliff is made of very week sandy conglomerate. It is glacial debris that wasn't compacted into actual stone. We have similar geology here in Washington state where deadly landslides are the result of the erosion induced fracturing.

Park's Chief of Interpretation, what a title.

What an incredible thing to witness. Nature doing it’s own thing. Thanks for sharing.

[leiag]

that's what Geologist's, call a "moment in geologic history"

[charlesuding]

Oh, something is happening. I must scream like an idiot.

nevermind the Volcano right underneath you.

Michigan has its own natural way of repelling fudgies. :)

That was great to watch, thank you...I love the great lakes and that water at the beach was so clear, would love to take a swim.

the lake just got a little bit bigger time to revise those maps

There are great charter tours on the lake to view the rocks. A very amazing and beautiful area to visit; been there many times.

😞😭It’s sad to think that with that kind of erosion, it won’t even be there in the future (of course you & I won’t be here either). 😭
