Ya it was from one slam. It was my first run that day. I was going at a decent pace but nothing crazy fast. Was not a real hard run either. I just popped a bs 180 off a little roller, apparently miss judged the amount of air I would get and landed half way around. When my board caught it kicked it out and just landed right in the middle of my back or some hard pack snow. Was not doing anything crazier or harder than my normal riding. Guess I landed just right for it.
owwwww, when I heard that i winced. thats usually how I fall: catching edge after a kicker or a drop
