Our Philosophy towards Diversity, Equity and Inclusion
The Silverton Avalanche School embraces and values diversity when it comes to race, class, ethnicity, religion, sexual orientation, gender identity and expression, mental and physical ability, and age. In order for SAS to achieve its mission “to reduce avalanche accidents through education”, we commit to celebrating diversity, working towards equity, and practicing inclusion in all of our work. SAS was born in a hard scrabble mountain town that has had a challenging economic history. Out of this history is a respect for all living beings.
- Diversity: SAS understands and values two simple truths: 1) there are many ways to experience and spend time in nature and the outdoors, and 2) our public lands and open spaces belong to all of us. For SAS to reach its mission, we must celebrate diversity in the outdoors and actively work to ensure all people and communities have encouragement and opportunities to safely explore the natural world.
- Equity: SAS understands that not all students start on equal footing when it comes to opportunities to experience the outdoors and strives to close the equity gap in our advocacy and programmatic work.
- Inclusion: SAS will employ best practices to foster an inclusive environment, striving to ensure a variety of perspectives, individuals, and organizations are welcomed and valued in our meetings and activities, particularly at the leadership level.

Spending his childhood, unsupervised, at the Santa Fe Ski Area Jasper’s love for snow began at an early age. Years spent ski racing laid the groundwork, but winter storms and cancelled races became more fun than bashing gates and competition. As a natural progression Jasper began backcountry skiing across the American West. With 16 seasons of off-piste experience Jasper makes Silverton his home where groomed runs are almost as rare as stop lights.
His affiliation with Silverton Avalanche School began as a student, and was followed by an internship in 2018. He is now SAS faculty for Recreational Track courses, an AIARE certified instructor, and holds a Pro 2 certification. As SAS Outreach Manager he organizes special events such as the 4 Corners Snow and Avalanche Workshop.
Jasper is a Professional Member of the American Avalanche Association and the American Mountain Guides Association. Through the AMGA Jasper is an Apprentice Alpine Guide working towards Mountain Guide Certification. He is an EMT with Silverton EMS, member of San Juan Mountain Rescue, and works with Center for Snow and Avalanche Studies monitoring research plots across Colorado. With a humble obsession for snow he is most often focused on the frozen world, but sometimes his mind wanders to the sweltering heat, delicious olives, and flamenco music of Southern Spain.

Coop started teaching with us last season and brings a great mix of education and guiding. Professionally speaking, he has facilitated many circles of students with Northwest Outward Bound School while leading mountaineering expeditions. During the winter months he can be found chasing snow, and passing on his passion for education and the backcountry through teaching avalanche education for in southwest Colorado.

Pro Program Lead Instructor
Elizabeth is a Full-Time Paramedic with Silverton EMS and a Mountain bike guide based in Moab, Utah for Western Spirit. She had guided trips in Utah, Colorado, Arizona, Wyoming, Utah, Montana, Oregon, California and Washington, and Canada. She teaches Avy education all over the state of Colorado and has spent 5 winters in Silverton teaching, working in EMS, and skiing. She has worked for Telluride Ski Patrol for two years.
Elizabeth’s favorite part about the skiing community is that she’s a butt girl. Skier butts are her favorite.
Elizabeth says she teaches selfishly because it keeps her fresh, but that she also loves teaching because it hasn’t been long since she was in her first avalanche class. There is a process to it all and she hopes that in sharing it, it’ll keep folks from making similar mistakes.
Elizabeth loves to ski and learned to love avalanche education secondary to that passion.
Ryan Howe (Howdy)
patroller and educator. Epic failure, success and the patience of mentors have allowed me to build a
solid foundation of operational experience and a desire to give back to the trade.
Avalanche education provides a unique opportunity to partner mentors with students and trade
professionals at different stages in their trajectory. I really value the chance to give back as an educator
and mentor while learning from students and the experience at large.
These days I make a living as an operations manager at Telluride Mountain Guides
(telluridemountainguiding.com), an avalanche worker at Telluride Ski Patrol and a faculty member at
Silverton Avalanche School teaching Pro-1 and Pro-2 curriculum.
He seeks to share this joy by offering tools that help enhance accessibility, improve decision
making, and ultimately empower more fun and future learning.
From learning to walk and ski simultaneously, skiing has been a guiding force for Aaron
throughout his life. He began ski instructing in high school on the small hills of MA, later moving west to earn a BA in hydrology and atmospheric science from the University of Colorado. Following graduation, his technical training accelerated during a four-year stint of climbing and skiing in the Tetons. He learned how to tie together the technical side with critical interpersonal and communication skills while working with students in outdoor education. As a guide and instructor, Aaron has led expeditions throughout the Four-Corner region and Alaska.

I started out taking my passion for the mountains and realizing that I love to share that stoke with others. Most importantly I love to share my knowledge, every guest, client or student of mine has something to teach me and I hopefully have some mountain knowledge to share with them. It is a slow process, there is no magic bullet and it requires patience, humility and an open mind. The mountains don’t care how much you know, or how much experience you have, we need to be guests and tread lightly, soaking up every little lesson and piece of information that we can discern. I love that we get to approach life with humility and a learners mindset. We get to question, we get to predict, we get to teach and ultimately we get to learn.
I realized that I needed personal Avalanche Education on my first backcountry ski tour in college. I have grown up with skis on my feet, pretty much as soon as I took my first steps, my parents had me skiing between their legs. We took avalanche education courses in middle school and high school, however any time we were in avalanche terrain either a mentor or a ski patroller was doing all the route finding, decision making or mitigation work. Stepping beyond those experiences, and realizing that I was in control of my own destiny forced me to re-evaluate and take a step back. There was a lot to learn and I really didn’t like relying solely on others to help me make decisions in the backcountry.
Watching and helping others learn and succeed in something they are passionate about drives me. Whether that’s coaching high school climbing or teaching avalanche education, I hope that through teaching, my students will walk away with a new midnset and a lens through which they view the world. I try to inspire critical thinking and encourage everyone to love what they do but not take it for granted. Snow is an incredible yet complex medium. Avalanche education is a multifaceted program requiring analysis of human psychology, decision making our natural world and the unparalleled stoke of skiing powder. It’s complex and thought provoking… Plus its freaking rad!
I love sharing long days in the mountains with new and old friends alike. I’m either out skiing, climbing, working as an ecologist or hanging at home reading and cooking up some new and hopefully delicious meal. See ya out in the mountains! Share the stoke and stay safe out there

I didn’t so much realize I needed personal avalanche education as I was told I was
getting it… My journey in avalanche education began as a rookie patroller at a mountain with an
active avalanche mitigation program. I didn’t so much REALIZE that I needed personal
avalanche training as I was TOLD i was getting it. Avalanches became my profession then, and
remain to this day.
I am motivated to teach avalanche classes because I believe it is my responsibility as a
professional to give back to the community that has given so much to me. Other people put
energy into my growth as a professional, and I owe it to others to pass that knowledge on to
