Adam Frelin’s artwork is inspiring. This happened at a quarry in upstate NY last weekend.
Here’s some history on the firefall, Here is Adam’s page on it. The rest of his site is worth the time too 
.
Here’s a picture that will give you a sense of the fire’s scale. They burned 250 pallets on a graded cliff in the quarry. The whole thing took about 5 minutes. Adam likens it to watching heat lightning, or snow falling. I think it’s beautiful.
