Professional Snow and Avalanche Workshop (PROSAW)
The in-person session will be held at the Eccles Center Park City (1750 Kearns Blvd, Park City, UT 84060).
If you are attending virtually, the livestream link will be sent at the end of October. Livestream sign ups end October 31st.
Join us for the 18th Annual Professional Snow and Avalanche Workshop (PROSAW), where Utah’s avalanche community will team up with snow professionals from around the west to share avalanche knowledge. The goal of the PROSAW is to provide continuing education for avalanche workers across the country by sharing case studies and stories from different operations in different snow climates with information to help them in their day to day jobs. The workshop will follow the spirit of the International Snow Science Workshop of merging theory and practice. Presenters will include patrollers, backcountry guides and forecasters, highway forecasters, SAR personnel, snow scientists, researchers, and more. The format will be 15-minute presentations followed by Q&A.
PROSAW is an all-day, two-part workshop; everyone is invited to join for both sessions on November 1st. The morning is dedicated to Utah-specific presentations, while the afternoon addresses stories and lessons learned nationwide.
The schedule is below, it is subject to change. Underlined titles are liked to associated research.
