Refreshing ‘Ologists: Avalanche forecasting challenges in a changing climate

August 10th, 2019 by Ellie, Mono Lake Intern

Join us on Wednesday July 14 at 4:00pm in the Mono Lake Committee gallery for Refreshments with Refreshing ‘Ologists. Sue Burak, snow scientist and avalanche forecaster, will be here to discuss how climate change is producing unusual avalanches. If you can join us for this free talk, please register here!

Recent avalanches in the Sierra have been unusual. Avalanche activity in 2019 began in early January and continued through June when a wet slab avalanche released above Tioga Pass Road and deposited mud and rocks onto Dana Meadows. Sue will explain why this avalanche happened through exploring the difference between wet snow and dry snow avalanches, and then discuss how climate change presents new challenges to avalanche forecasters. As an added bonus, she will offer some predictions for the winter of 2020!
