These two are idiots when it comes to avalanche awareness. They may be badass riders...but who gives a shit about that?
That is not how you safely cut a slope. If that is what he was trying to do.
Clearly active wind loading. Avy conditions are changing by the minute. Any assumptions they made before starting their tour are out the window. Should have had a plan B before starting and willing to back off once they saw the wind loading. Based on their indecision of how to proceed after triggering, they didn't think this through ahead of time.
They are on a thin snowpack near the trigger point - always weak.
Says "that's what I was afraid of". Wait...if you were afraid this would happen, WTF are you doing on that slope? You must not be that confident the slope is safe from the obilex (which isn't intended to make this slope safe to ski on). Your confidence level better be higher than that if you are going to risk a road and infrastructure. Sounds like they knew there was a good chance this could happen.
Their dumbass hindsight continues - "Fuck, we buried the road, hope no one was on it." Those are the thoughts you should be having long before you are standing at the top of a line like this.
I don't know if this meets the legal standard of reckless, but for sure was reckless by a common sense standard.
Genuinely glad no one was injured or killed, including the two responsible. But, seriously, get these morons out of the backcountry before they do injure or kill themselves or someone else.
