Spotted In Denver: Alien Spaceship or Cloud of Smoke?
This cloud of smoke gathered from the most devoted marijuana tokers in the state.
The clouds form in the shape because they're formed on the downwind side of a mountain or range, according to 9News.
Other imaginations determined that other than an alien spaceship, the lenticulars cloud also resembled a whale or a slug. It's nice to see our lungs, I mean imaginations, are so creative and hard at work.
