The first thing I thought when I saw this video of a roll cloud moving over Lake Michigan was literally, "What the heck is happening on Lake Michigan?" I have never heard of a roll cloud and I've been here my whole life.

But one was filmed by a guy named Ken Temple on June 11, 2016, who was standing on a dune, and captured all of its beauty:

The video has been viewed 2.4 MILLION times and has generated a lot of reaction from Michiganders:

What IS A Rolling Cloud

Although I thought it was some kind of alien cloud, someone had a better understanding of what the rolling cloud formation really is:

The popular term for arcus. A low-level, horizontal, tube-shaped arcus cloud associated with a gust front of a convective storm (or occasionally a cold front).

But this doesn't just happen on the Great Lakes, as apparently, someone in Europe experienced the same phenomenon:

I live in England and a few weeks ago, there was a cloud very similar to this coming in from the Irish Sea over Blackpool promenade. I watched it as I drove along the prom, lots of people stood watching it too. I didn’t think they existed here but I’m convinced it was one of these.

LOOK: Lake Michigan Beach Named One of the Best 'Secret' Beaches in U.S.

Northern Michigan's South Manitou Island has been named among the best 20 "secret" beaches in the U.S. by Southern Living Magazine.

Within Sleeping Bear Dune's National Lakeshore, South and North Manitou Island are part of an island chain in Lake Michigan that extends north to the Straits of Mackinac. 

According to the National Park Service, "The island consists of a ridge of tilted layers of limestone, buried under a blanket of glacial debris. It features unique sand dune formations, 10 miles of beaches, and a grove of old growth white cedars that date back over 500 years."
