While hiking along a steep slope in ColoradoI was crossing a slide when I lost my footing, next thing I know I was sliding downhill and the going was getting rough. I managed to get on my back and had my feet out in front of me, I saw one tree to my left that might stop me before a sheer drop. I was able to get slowed down a little and lean over and plant my foot down. I pushed some dirt/rock up right before the tree and then hit the tree hard!
It held and I was able to get stopped and move to the left and away from the slide. I had slid about 40 feet.
I ended up jamming one finger, my hands were shredded and a couple fingernails were ripped loose, but other than that I walked away. Another 10 feet and it would have been a 30 foot drop to the bottom of a creek bed.
That jammed finger hurt for two years after that.
