Weather Stations

Weather Stations provide the GNFAC forecasters with information on snowfall, wind and temps from around the region. The Weather Log summarizes this daily.

Avalanche Education

GNFAC partners with groups around the region to provide evening avalanche classes, plus full day and multi-day courses, including some weekend field days. All our class offerings, along with courses from other providers, are on our Education Calendar.
