I started on to a very scraped over icy blue run today. As I side slipped down the first bit and my heart pounding, the video of falling crossed my mind. I can’t imagine that any self arrest would have allowed me to dig in to that ice. Made it down ok, just a few more grey hairs and possibly strain on my cardiovascular system lol! But curious, what if you are on a really icy hard packed scraped out area, how can you stop on that??
