South Dakota is full of beautiful and majestic things. The Black Hills, the Badlands, the Missouri River, and Falls Park, just to name a few. But one thing not found in the state of South Dakota is volcanos, thankfully. At least, not yet.

That being said, in a video that has been making the rounds on the internet, a mysterious type of underwater volcano sand can clearly be seen. What is it? Take a look at the video and decide for yourself.

See the Mysterious South Dakota Sand Volcano

Jeremy Smith took the video in Aberdeen, South Dakota late last year and it has perplexed people all over the internet ever since.

The strange formation was spotted by Smith in Wylie Lake and looks like an underground volcano of sorts, spewing sand into the bottom of the lake itself.

Smith visited the lake many times and noted that it began as a small depression in the lake bed, but eventually grew to over ten feet in width.

The dock for Wylie Lake was pulled before last winter, so no one knows if the mysterious sand volcano is still there, but you can be sure onlookers will be checking the area this spring.

Watch the YouTube video from South West News Service below to see the mysterious volcano sand yourself.
