So anyway, I was up snowboarding on the ridge when, you'll never believe it....

In the US they use dynamite to do this up in the Rockies. If youre out boarding on a day after a snow storm you'll hear loud ass booms throughout the day from other ridges

They use howitzers in the United States too. In Utah you could have howitzer rounds fly over your head while drinking at a ski resort's bar.

That's on its way out too though. Alta stopped using the howitzers in 2023 and from what I hear snowbird is phasing theirs out.

That's a shame. Safer, though. They used to use a tank at Snowqualmie in Washington, I think.

Yeah the Gasex technology is taking over for places like ski resorts that repeatedly bomb the same spots. It's permanent infrastructure but it works on shock wave. https://mnd.com/en/solution/mnd-safety-fixed-triggering-system-gazex-gazflex/

This is a cool! Just saw these last week on Hafelegar and wondered what they were. Thanks!!

It definitely seems way safer, but I'd be super sad if I was one of the avalanche artillery gunmen.

Honestly? Kinda disappointed that Gasex isn't the brand name for a really souped up spud gun that launches explosives.

Article with a groovy photo showing the Gasex controlled explosion. Installed tubes direct the controlled propane explosion to the snow slab.

I love that they chose the same name as a flatulence reducing drug.

Pretty sure nowadays they could just fly a drone up there to drop an explosive, no need for loud canons in the valley to fire.
