There was a nice, thick layer of snow protecting the marble steps of The Rotunda this weekend and some snowboarders decided to see if they could catch some air off them.
I don't know who these people are. The video was taken by someone who happened to be walking by and was sent along to us by someone else.
I am not endorsing this. In fact, there's a huge statue at the bottom of those steps and had the boarder not fallen during his landing, I'm afraid he might have hit the base. The standard disclaimers apply here (do not try this at home, do not try this at UVa, do not do this ever).
