The Colorado Department of Transportation and contractor partner, Midwest Rockfall, Inc., recently completed the installation of new avalanche control equipment above U.S. Highway 50 Monarch Pass, about 15 miles east of Poncha Springs, near the Monarch Ski Area.
As part of CDOT’s safety initiative, this new remotely controlled avalanche mitigation system, named Gazex, will improve safety for CDOT employees and ski patrol workers who assist with mitigation operations.
Instead of handling live ordinances or ammunition, Gazex is a permanent installation on the mountain that uses compressed air and gasses to create a concussive blast to trigger a snow slide under controlled conditions. The system is triggered remotely by operators from a secured distance creating a safer operation.
The system, also improving safety for the traveling public, will allow for increased frequency and nighttime or early morning operations when there are fewer vehicles on the highway.
Avalanche mitigation efforts with this system will prevent large accumulations of snow and decrease the risk of unexpected, natural avalanches and long delays due to cleanup and extended closures.
The U.S. 50 avalanche control project included installation of a control shelter, which houses equipment needed for the operation of three remote avalanche control units above a known snow slide path near the Monarch Ski Area, between mile points 201 and 202. Similar remote controlled systems are also used on U.S. 40 Berthoud Pass and U.S. 6 Loveland Pass in Colorado.
