"Top notch Avalanche education from a top notch educator right in your backyard boise! Boise has been needing this for a looooong time."

Greg Call, Professional Photographer

"This guy is a phenomenal instructor and this is a great opportunity to learn about snow."

Dave Bingaman, Avalanche Forecaster

"I learned more during my Avalanche Level 2 course with Chago than in the previous 15 years of backcountry skiing."

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!"

Vince Boelema - Ski Instructor and staff trainer. Sem Walls - Ski Instructor Examiner and New Zealand National Demo Team

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

Ryan Burr - Elementary School Teacher

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.

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

I highly recommend Chago's class. I felt really lucky to be able to take a class from him so close to Boise. The class was really thorough and he takes pride in making sure that you have the tools and the knowledge to be safe in the backcountry.

Paul Whitworth, Prestige Skateboards Shop, Boise

I would highly recommend Avalanche Science's Level 1 course for those looking to get into the backcountry for the first time as well as experienced backcountry navigators.

Drew Dodson, Boise Weekly Reporter

I am incredibly happy that I took my Level 1 with Avy Science. The small class size, quality course material rooted in data and facts, and an instructor passionate about snow science and avalanche education put this course above all others

Robby Milo, IT Specialist

Chago was incredibly knowledgeable and passionate. It is hard to not engage with the material when the instructor cares that much


Chago knows his material and has been studying avalanche science for many years. This experience shows in his avalanche classes as he explores different hazards on different terrain, changing weather impacts on snowpack, and rescue strategies.


As an avid backcountry user, it was nice to capitalize on the knowledge of Chago and Nico to get an in-depth understanding of the snowpack. Instead of just testing for whether something was stable or not, understanding what was going on during the test to make a slope stable or not was a huge takeaway for me.


Chago is one of the best instructors I have had in any type of field class. I say this because he is passionate about the information and material he is teaching. Sharing that passion was inspirational, and it made the class fun and the material easy to understand.

Ben Luedtke

Great teachers explain the "why", not just the "what". This allows willing students to immediately comprehend and commit material to memory. Chago is this kind of instructor! He understands snow at a level that allows him to answer detailed questions and discuss theory. And when you combine his teaching skills with his passion for snow sport, the learning is indelible and the fun paramount! I'd gladly take another course or pay for a guided trip with either instructor any day.

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 and riders, as well as snowmobilers. Participants will learn about decision-making, situational awareness, risk assessment, and the fundamental physics behind snow metamorphism—why avalanches happen.

Avalanche Education Redefined

Avalanche Education Redefined

Effectiveness of the instruction is enhanced by limiting lectures and field work to very small group sizes of six participants per course.

Avalanche Education Redefined

Avalanche Science courses consist of four hours of online instruction, eight hours of lecture by an expert snow scientist, and 20 hours of field work amid some of the best backcountry glades skiing found anywhere.
