Dave Kelly's career on snow has included stints forecasting for a remote narrow-gauge, trans-national railroad on behalf of the Alaska DOT. He's also put in time at Turoa, one of the largest ski areas in New Zealand. And for 16 years, he worked as a ski patroller at Alta. He joined the Utah Avalanche Center in the 2022-23 season as a forecaster for the Salt Lake area. And he says it was the challenge of forecasting for bigger terrain that drew him to his new gig. Kelly joins us to talk about making the transition from an operational forecaster to a public one. And we also try to wrap our heads around the mysteries of radiation recrystallization.
