Today we’re talking about the science of snow, the art of avalanche forecasting, and what every backcountry traveler can be sending in to their local avy center to help them produce more accurate forecasts.

Our guest is Zach Guy, who is the lead forecaster for the Crested Butte Avalanche Center. Zach has a master’s degree in snow science from Montana State University, he’s served as the director of the Flathead Avalanche Center in Northwest Montana; and he returned to Crested Butte in the fall of 2020 to take over as the CBAC’s lead forecaster.
