Avalanche Education Redefined

Avalanche Science's courses are designed for people seeking complete instruction and preparation for traveling safely in avalanche terrain, including backcountry skiers, boarders, and snowmobilers.

Michael Lanza, Creator of TheBigOutside.com

"Chago combines his PhD level snow science background with his deep passion for skiing and people to deliver education that you will not forget. It's not often that courses are as enjoyable as they are educational. Highly recommended!"

Skiing with Chago is like purchasing a BMW. You know you are going to be safe and have style"

I just finished a course with these guys. Very passionate and great instruction.
Mores Creek Summit is definitely a hidden treasure you’d get to explore as an added bonus.

Ryan Bentley - Program Manager at Youth Dynamics Adventures and Soldier Mountain Ski Patroller

Chago connected sub-nanometer phenomena (shape and properties of water molecules) through millimeter scale (sintering, faceting) to explain what triggers an avalanche hundreds of meters in size. This was fascinating.

Brendan Flynn - Completed Avi L1 during his first 3-days of Backcountry Skiing ever!

Chago was fun to work with and gave me instructions that made me feel confident and aware.

Lucy Hedges - Completed Introduction to Safe Travel In Avalanche Terrain and Avalanche Rescue Course
