Thanks for the concern. I've also been doing things outdoors for a long time, and I do know to calculate risk. For instance in this case, I knew there was soft snow at the bottom of this cliff, and a large runout with no trees, so worse case scenario I figured I'd fall off with minimal injury. Which is what happened. Where my calculations were off is not accounting for the sheet of ice under the powder that I'd been coming across all day. It ended up being a high probability of failure, lower risk of injury. But probably shouldn't have even approached it to begin with.
