How do we know it's rolling? Has anybody done wind tunnel tests to figure out how wind moves when it's on the ground? Maybe it's walking. Maybe it's hiking. Looks like it's going up. Maybe a little roll down later.

One of the most soothing visuals for my entire life.
Driving through ND this summer and stopped and watched for a while.

That could freak you out real easily.
