Holly Yocum
President

Holly is fortunate to have spent her life playing in the Sierra Nevada.  A lover of any form of sliding on skis in the snow, Holly has been a full time backcountry user since the turn of the century.  Upon learning that alpine touring is supported by a network of mountain huts in many countries, she combined a love of travel and backcountry skiing to pursue ski tours in Norway, Morocco, the Alps of France, Switzerland, Italy and Austria. 

Holly became interested in the dynamics and dangers of avalanches after the Alpine Meadows avalanche in 1982 and as a result of her travels in avalanche terrain during her backcountry adventures.  She believes that education, awareness and access to avalanche advisories have the power to alter and improve decision making, allowing for safer backcountry use.  

Holly lives, works and plays in Incline Village, using her degree in geology to bore her friends on long trail runs.

Mark Bunge
Vice President

Mark grew up skiing in the lowly Appalachians, addicted to Powder Magazine and Greg Stump films, and dreaming of a day when he could live and play out West. That dream came true in 2002 when he quit his job and drove from Maryland to Wyoming. Brimming with excitement and naive confidence, Mark charged into the Jackson Hole backcountry with little knowledge of avalanche terrain and no safety equipment whatsoever. He avoided serious consequences thanks to dumb (literally) luck alone.

After moving to California, Mark wised up and belatedly began studying avalanche safety. He joined the Sierra Avalanche Center to help fellow Tahoe backcountry enthusiasts safely enjoy the amazing terrain that our area has to offer, avoid the bad choices he made, and come home safe due to smart, informed decision-making, not sheer luck.

Mark works as a political and market researcher, and hopes to help the Sierra Avalanche Center solidify its fundraising and expand its educational mission. He lives Truckee with his wife and two ferocious Chihuahuas, and spends his free time skiing, playing volleyball, rock climbing, and falling off his mountain bike.

Bob Moore
Secretary

Bob recently retired from the US Forest Service after 37+ years. He spent the last 25 years as the Winter Sports Specialist on the Truckee Ranger District. Among his duties was the administration of the permits of the local ski areas (Alpine Meadows, Squaw Valley, Boreal, Donner Ski Ranch, Royal Gorge) on National Forest lands and the avalanche forecasting program (as it was known at that time). He coordinated the military artillery used in avalanche control for Region 5 of the Forest Service (California). He usually spent much of the summer months managing large fires as an Operations Section Chief or Safety Officer across the west.

Professionally Bob was one of the early members of the American Avalanche Association, served two terms as a Director with Tahoe Nordic Search and Rescue and was one of the founding members of the Avalanche Artillery Users Committee of North America. He was nominated and elected to the B-77 ANSI committee for tramways representing recreation within the Forest Service. Bob was the advisor to the Forest Service Regional Office in explosive and artillery use for avalanche control and winter sports.

In 2005 he put together the concept of the Sierra Avalanche Center which stared with Brandon as a volunteer forecaster to assist him in the forecasting duties. Previous to that Bob was a one person shop putting out avalanche advisories when the hazard was HIGH or above for 20 years. He served as the Forest Service advisor/representative to the board in the early years ensuring that Forest Service support and resources were available. He was the supervisor of the forecasters until his retirement setting the direction of the program.

He has been married for 33 years, has two grown children and 1 Golden Retriever Dog who travels with him in the backcountry. He has lived in the Truckee/Tahoe area for 38 years.

Dustin Evans
Director

My grandparents moved to South Lake Tahoe in 1961. I was fortunate to be born and raised in South Lake Tahoe. As a kid, I started skiing for Heavenly and caught the bug. As a ski racer, I had the opportunity to enjoy many of the big resorts in the West Coast. I was even able to recently ski in Antarctica. Now, I enjoy skiing with my family, including my two children, Elle and Waylon as well as my wife, Kim. I also love to snowmobile and spend as much time as I can in the backcountry. I have two primary jobs, including managing a property management company on the South Shore and running a telecommunications company. However, I am able to manage my time and feel fortunate that I can spend as much of it as I can enjoying the Sierras.

Eric Petlock
Director

Eric joined the Sierra Avalanche Center board in the fall of 2014. Eric is an avid skier who spends as much time as possible skiing the backcountry around Donner summit. When he’s not chasing untracked powder in and around Sugar Bowl you might catch him exploring new terrain just about anywhere along the Sierra crest. He has worked as a professional ski patrolman, a mountaineering guide and is currently pursuing a new career as a heli skiing guide. This season you may be able to catch up with him in the Ruby Mountains of Nevada or in Southeast Alaska finding the best snow for his clients. Eric has also worked in finance and public policy making him a well-rounded member of the SAC board of directors.

Zach worked as a ski instructor at Squaw Valley and brewed beer at the Lake Tahoe Brewing Company where he met his wife Danielle. His passion for spending time in the mountains and his interest in snow led him to become a Ski Patroller. While doing avalanche control work along the Sierra Crest the mystery powerful pacific storms lured him back to school where he completed his bachelor's degree in Atmospheric Science at the University of Nevada, Reno. Zach works at NOAA’s National Weather Service where he spends his workdays forecasting the weather in the Sierra and his days off skiing as much as possible.
