but yes, ski resorts use explosives in targeted areas to make them slide
Right, but I was wondering if it would help our current scenario, since it results from multiple deep weak layers dating back to late Fall.

Education & avoidance is better.
Are you suggesting blasting all BC areas in the state!? That's a lot of dynamite, or whatever explosive they use.

no it was just a thought experiment

Does an avalanche due to weak snowpack make a slope safer? Though not practical, one solution to address CO weak snowpack is to safely trigger massive avalanches everywhere? That way, future snow can accumulate on top of stable layers? Just asking out of intellectual curiosity.
But ski resorts and CDOT repeatedly blast avalanche areas and get results after every major loading event. Its not just a one-and-done fix the weak layer and you're good to go, unfortunately. To do this in the backcountry would be impossible, and may even lead to more accidents due to the assumption that it is safe to send because its controlled. Not to mention the liability of controlling hundreds of thousands of acres with no ability to close terrain. I could keep going, but its better to accept the risk and base decision off of knowing the consequences of what can happen when things go wrong

That's what Dr. K does with his Rock-down-a-Couloir avalanche mitigation strategy.

Immediately after a slide, yes, it's often safe.

As for that slope being safe for the rest of the year? No, in fact it's usually the opposite. Thin snow= weak snow. So after a slide, the snowpack will generally be thin and will once again grow weak, resulting in what is termed "repeater slides". There are several places in my local backcountry that I've seen slide at least 3 times so far this season.

Wow that’s big. I saw the Sherriff and SAR On the way home from Vail. Looks like another fatality. The snow was great but it’s not surprising the other side of the rope would slide on a day like today.

I remember seeing a bunch of big funnels and massive pipes in the Alps.
They use propane burst, like a potato cannon or ground burst simulators some of you might be familiar with, to keep slide areas along the highway safe.
It's a big installation, not for backcountry, but I assume they've got radio receivers so they can just set them off from time to time.

They also have those here protecting Hwy 40 on Berthoud Pass, Hwy 6 on Loveland Pass, and I-70 around the tunnel.

Our snowpack is telling us to stay away and yet we continue to go. I know backcountry powder is tempting, but please be smart and safe. This week has been emotionally exhausting.
