Guess it was a small wind slab he encountered on the way up.
I imagine UDOT is understaffed and they want to strech their staff as far as it could go. I see nothing wrong with him being out alone. He knew what he was doing Sounds like it was just a case of terrible luck. Says he died of trauma during the slide. A partner wouldnt have helped. I probably tour 50 percent of the time alone. You just have to use your head and not take unnecessary risks, knowing there might not be someone there to save you. And besides in the Wasatch, touring solo doesnt necessarily mean alone, not that you should expect to be rescued by a stranger.
