Helon Hoffer .png

Growing up in the Northeast Kingdom of Vermont, he spent most of his summers hiking in the White Mountain National Forest. In winters, he learned to ski ice, crud, and bumps. After four years at Bates College, he moved to the Mount Washington Valley and began his education in climbing and steep skiing. Caretaking at several backcountry facilities taught him the art of pack boarding, composting, and reading birch glades. In 2015, he joined the Forest Service as the Androscoggin District Trails Manager in the summer and a forecaster for the Mount Washington Avalanche Center in the winter. Besides coordinating heavy-duty rigging for trail work and running wintertime search and rescue operations for the windiest hill in America, Helon is working with partners to better the tree-skiing opportunities on public lands. During his free time, Helon enjoys teaching his son about bonsai care and new ways to tease their dog.

The program has directly reached over 200,000 students in Utah to date and has spread around North America.  Craig's legendary enthusiasm and communication skills keep him in high demand on the avalanche lecture circuit and television appearances.

Sarah Carpenter

Sarah has a passion for the outdoors.  She’s been working in the field of snow and snow science since 1998, when she started as a ski patroller at Bridger Bowl in Bozeman, MT.  As an owner of the American Avalanche Institute, Sarah teaches avalanche courses throughout the west.  Sarah also works as a ski guide in the Tetons during the winter, sharing her love of skiing with others while wearing a huge smile on her face. During the summer and fall, Sarah works as a mountain guide throughout the western US, as well as internationally.


Sarah lives with her husband on the west side of the Tetons in a straw bale house that they built together. Spending a year building a house convinced Sarah that climbing mountains, skiing, and working in the outdoors was significantly easier than the job of a contractor, architect, or carpenter.

Weston Deutschlander


Weston is one of the smarter New Yorker's and fled the state as soon as he could. After arriving in Utah, the snow addiction took a firm hold. Once he learned the freedom of a beacon, probe, shovel, skins and a good partner, he started venturing further and further off the beaten path. Today Weston spends his summers and winters guiding all while trying to play as much as possible on the side.  I'm pretty sure River is guiding Weston in this photo.

Mark Mueller

IMG_0698 (1).jpg

I grew up just south of San Francisco and started skiing when I was in high school. With no clear path I moved to Tahoe, got a ski area job, and found my tribe. I became interested in the winter backcountry which included getting to know something about avalanches. While at Alpine Meadows working in the rental shop I got caught and injured in a serious avalanche when I was 20 years old- I was a very lucky young man. This only spurred by interest even further and led to getting a job on the Squaw Valley Ski Patrol after spending two years at Colorado Mountain College Leadville in the Ski Area Operations program. I spent 15 years at Squaw with 12 of those years as Ski Patrol Director. After I left Squaw I learned of the new highway avalanche forecasting program in Colorado. I spent a winter patrolling at Wolf Creek before hiring on with CAIC and have been with the CAIC highway forecasting program there for 25 winters and counting. I'm nearing retirement, but have a couple more winters in me before heading out to ski the world with my wife Sandy.

Mark has been forecasting for the FAC team since 2015. Mark has over 20 years of snow safety and avalanche forecasting experience. This experience includes days lamenting over depth hoar at Berthoud Pass in Colorado as a guide and ski patroller to his time in Montana as a professional patroller for Whitefish Mountain Resort, a forecaster for Burlington Northern Sante Fe in Essex, MT, and the National Park Service with the Going-to-the-Sun Road avalanche program in Glacier NP. Mark has also been an avalanche educator for 24 years and is a professional member of the AAA. In the summer, Mark trades his skis for a beloved pick mattock as a trail crew supervisor in Glacier National Park where he has been working since 1995.

Evelyn Lees

Evelyn Lees has been a forecaster with the Forest Service Utah Avalanche Center since 1991. Before that, she worked as a meteorology field technician for a cloud seeding project in Utah. Evelyn spends her summers as a senior guide for Exum Mountain Guides in the Grand Teton National Park. She has been on mountaineering expeditions in Tibet (Mount Everest), Pakistan, Alaska and South America. She has degrees in both Geology and Soils.


John Sykes


John started his career as an avalanche professional in 2011 working as a mountaineering guide and avalanche educator in Alaska. Feeling the draw to further his education in snow science John completed a MSc at the Snow and Avalanche Laboratory in the Department of Earth Sciences at Montana State University from 2016 to 2018. His research focused on decision-making in backcountry skiers by looking at GPS tracks and survey responses. At SARP John is continuing to research decision-making in avalanche terrain by developing new avalanche hazard maps and analyzing GPS tracks of heli-ski guides. The goal of his research is to work towards a new decision-making tool for both professional and recreational backcountry skiers based on the observed decisions of expert guides.

billy grew up in Trenton, NJ and went to college at Rutgers University in NJ. He got to Gothic in May of 1972 to work on a water quality study and at the end of the summer decided to stay and moved into an old 8 x 10 foot shack where billy lived for 8 years after first completing his last semester of college. In 1980 he built a house next to the shack and has lived there since. billy did odd jobs- fire fighting, dish washing, plumbing and electrical work, until taking over the accounting at RMBL (Rocky Mountain Biological Labratory) . billy started compiling weather records in 1974 as sort of a curiosity and has been doing so since then.

Roger Atkins


Roger has a background in the physical sciences and a passion for powder skiing. Although experienced at backcountry travel and well educated in the technical aspects of snow and avalanches, at the start of his guiding career, Roger found it challenging to make confident decisions about skiing specific slopes. Competence depends on who you are and what you know; becoming competent involves personal development. Roger’s goal has been to find methods that balance technical knowledge with positive human attributes to improve backcountry avalanche risk management.

Joe and Mike Royer

Mike, Francy, and Joe Royer

Mike, Francy, and Joe Royer

Joe was working at Snowbird in the early 70's and would travel to Marin, CA in the off season. I-80 was a two lane road and always an adventure, a relief to make it to the next town. The Ruby Mountains were a stand out, and had to have some skiing. The exploring came in the mid 1970's and we are still exploring today. Seems like we are always learning something new. Some way to ski new terrain, or some way to make the experience better for our guests. The business continues to be a work in progress.

The greatest reward is being able to provide a backcountry experience to our clients and hear them say, "That's the best day of skiing in the my life!"

Mike grew up in the family business of Ruby Mountain Helicopter Skiing in Lamoille Nevada. He was fascinated by every aspect of the business and spent his childhood winters helping wash the helicopter, taking out the garbage and learning how to drive a snowcat. Mike has been mentored by some of the best guides in the country who have worked for Ruby at some point during the last 20 years and who have helped him develop into one of Rubies lead guides. Continuing the passion, mission and dedication that his parents Joe and Francy have been providing guests at Ruby Mountain Heli Ski since 1977 is Mikes goal moving forward. One of Mikes favorite things about the winters in Nevada is the family vibe the business brings from all of the Ruby staff to all of the guests who walk through the door.
