A couple of years ago we were riding Chair 8 at Mt. Baker which offers complete views of Mt. Shuksan and the ridge called "Shuksan Arm" that leads to the mountain from the ski area. This is out of bounds, but has lots of folks hiking the ridge and dropping down it, eventually re-entering the ski area and riding back up C8 to do it again.
Anyway, as we were riding up the lift we watched a guy ski down directly at a big cliff, I figured he would turn off but he kept heading right at the cliff and he eventually skied right over it,
did a back flip, and then pulled the cord on what I took to be a paraglider. He then soared around a while and I lost track of him. Later I saw what must have been him loading C8 for a return trip with a huge pack that must have contained the glider. It definitely blew my mind.
A picture of some of the ridge is below. I'm not sure if the cliff in the center was the one he used, but it looks like that.
