Crews will be utilizing helicopter operations in the Stinking Springs area of Hoback Canyon to do some general maintenance and refueling of the avalanche infrastructure known as the O’Bellx units. These units use explosions to trigger smaller, controlled avalanches to prevent dangerous, uncontrolled conditions. The O’Bellx units are remotely operated by computer and are installed and removed by helicopter. The work will cause intermediate delays for traffic of up to 15 minutes at a time.
