I am truly amazed that there isn't an incident like this every weekend on trails like Osgood, a truly tedious path. I was on a really tedious trail last week on Medicine Bow Peak in the Snowy Range. Brutal boulder "hopping" during the final summit push. And this is at 12K feet. They don't use yellow paint out here to mark the rocks, just the occasional cairn. Long's Peak is the exception.
