Mark Dundas is the newest avalanche specialist to the FAC team. Mark has over 20 years of snow safety and avalanche forecasting experience. This experience includes days lamenting over depth hoar at Berthoud Pass in Colorado as a guide and ski patroller to his time in Montana as a professional patroller for Whitefish Mountain Resort, a forecaster for Burlington Northern Sante Fe in Essex, MT, and the National Park Service with the Going-to-the-Sun Road avalanche program in Glacier NP. Mark has also been an avalanche educator for 24 years and is a professional member of the AAA. In the summer, Mark trades his skis for a beloved pick mattock as a trail crew supervisor in Glacier National Park where he has been working since 1995. 

Zach Guy
Director, Avalanche Specialist

Zach began directing the Flathead Avalanche Center in the spring of 2017.  He brought six years of forecasting experience with him from the Elk Mountains of Central Colorado, where he was serving as the director and lead forecaster of the Crested Butte Avalanche Center. He also worked in Crested Butte as the assistant snow safety director and as a ski guide for Irwin Guides.  Zach's academic foundation comes from a B.S. in geology from Western Washington University and a MSc in snow science from Montana State University.   Zach is AVPro, Wilderness First Responder, and Type 1 Explosive certified, a professional member of the American Avalanche Association, and has presented at numerous International Snow Science Workshops.  He grew up in Estes Park, Colorado, but has been studying or playing in the snow from the Cascades to the Tetons to the Rockies.  If there's not enough snow to ski on, then you'll probably find him riding his mountain bike or watching Will Ferrell movies.
