Got curious to learn more about Gazex for avalanche control since Alta plans to install several. Gazex was invented in France in 1988 so has been used in Europe for quite a while. There are over 2000 installations. A couple were installed by CDOT for the 2015-16 season. JH also uses Gazex. Crystal also has Gazex exploders.
AFAIK, Snowbasin in Utah was the first US ski area to install Gaz Ex. Saw one on Headwall at Squaw today.
Yep, Squaw installed Gazex last fall. Sounds like planning to install more in the future.
Snowbasin started using Gazex in 1999 according to an article from 2004. So it was in place before the 2002 Olympics.
The Gazex installation over Teton Pass has been there a while. Was mentioned in a 2006 thread.
Apparently there are other Gazex exploders installed in LCC and BCC. Snowbird bought one for UDOT in 2015 to use for the slope off Mt. Superior that is above the Lodge. It's a different version that uses hydrogen and oxygen that cost $200,000, including installation by helicopter.
Clearly Alta has been thinking about Gazex technology for a while since it was mentioned in the 2009 MDP.
