CDOT reports the mitigation operations over the weekend brought down 60 new feet of snow, which then spilled into the Riverside snow shed along the highway.

The avalanche filled the shed, which is designed to protect drivers over the slide path in case of a natural avalanche.

60 ft of snow on top of the roadway.

I wonder what "helicopter avalanche mitigation operations" involve. Are they dropping explosive charges? Are they firing 2.75" rockets? Hellfire missiles?

I always thought the recoiless rifle mounted in the back of a truck was cool. I'd love to watch a helicopter blow up the mountainside.

Depends sometimes they have cannons that are mounted in strategic places other times they drop tnt out of the helicopter

I was in Breckenridge last week and they were firing those cannons all week. We almost weren’t able to get to the Denver airport due to the avalanches around us

I remember seeing TV show a really long time ago about avalanche control. There was a permanant gun emplacement located at an avalanche prone area. I was a kid from LA and thought that must be the coolest job in the world. Hanging out in the mountains, firing a cannon, and getting to watch avalanches.

helicopter avalanche mitigation operations"


They started this here this year. Used to use a105mm howitzer. Helicopter system is called a Daisybell system

LINKThe DaisyBell looks like a megaphone pointing at the ground, and during usage it dangles underneath a helicopter.

quote:

Gas is ignited inside the DaisyBell, and the explosion from ignition creates force that is amplified and directed by the conical device. The pressure wave is what clears out snow and reduces avalanche risk.

The cannons are cool as all hell. We drove from Keystone to Denver one time and the road/interstate was shut down a while for the cannons to do their thing.

So we opened up the van, listened to the missiles, pissed on the side of the road and kept drinking.

Missed our flight home too.

Good times.
