Looking at the pics... That's a big hill.
Was he buried and asphyxiated or did he die from trauma?
Simple question, with all due respect.
Luke was a standup individual, hell of a nice guy and an amazing rider! I had the chance to ride with him a couple times and have some friends that we're really close to him. Honestly every time I saw him ride I was beyond impressed, he made riding steep and deep effortless and would hit 100'+ cornice drops, cliffs or anything that he found like it was nothing. He filmed with Alpine Assassins, Burandt and a host of other groups so you know he had skills! On top of that he was just a heck of a happy guy that just loved the sport and its a huge loss to the industry and our local community to have him gone.
I was not there but from what I heard:
On Saturday, he was up scouting area's with some guys filming some big drops and jumps off a number of spots. He was dropping the big cornice just below the lookout that runs out and down towards the horse coral. He had hit the drop twice before it slid on the 3rd drop it broke with about a 6' deep slide and took him all the way down the first slope and down the long second slope and buried him about 10' deep. I don't know exactly how long it took to get him out (not too long) but they did cpr without success likely due to internal chest trauma. He always wore an airbag but I don't know if it had been deployed. The rescue chopper got to him about 3 hours after the slide but was no help at that point.
He passed doing something he honestly loved and will be missed by many. RIP
