She started working with SMC in 2024 as a hiking guide and is looking forward to many more great adventures in the Sierra!

Growing up in South Dakota, Kanyon made frequent trips to Wyoming where he first ignited his passions for backpacking, climbing, skiing, and cherishing the outdoors as a whole. In college, a hunger for climbing led him out west to visit Yosemite for the first time. He was quickly obsessed with the Sierras as a whole. After college, Kanyon started guiding in and exploring the high granite expanses of the Sierra Nevadas. After three years of guiding, Kanyon retired to the quiet life as a wilderness ranger in Yosemite National Park. This will be Kanyon’s first time back to the other side of the wilderness permit, and he’s excited to be back. In his free time, Kanyon enjoys rock climbing, hiking, skiing, trail running, and reading.

Caber was born and raised in the small beach city of Santa Cruz and grew up hiking and mountain biking amongst the redwoods. He made annual trips to Yosemite with his family, which nurtured his love for the Sierra Nevada. He attended California State University, Fullerton, and earned his Bachelor of Arts in Theatre. While in college, Caber worked for his school, taking his peers on backpacking, hiking, and climbing trips around southern California. After college, Caber completed a thru hike of the Pacific Crest Trail and fell in love with backpacking in the High Sierra.

Colin grew up hiking and camping via family vacations and the Boy Scouts across 15+ national parks. He still remembers the nervous exhilaration he had when his parents let him and his brothers do the exposed hike up Angels Landing in Zion National Park by themselves. When he joined the military after high school, he thought he would need to largely leave the outdoors behind. He was wrong. As part of his training, he got the opportunity to take part in two month-long NOLS courses mountaineering in Alaska and instead discovered a passion for big adventure and challenge in the mountains. After eight years on active duty and multiple deployments as a Marine Infantry Officer, Colin transitioned to reserve status in 2022 to pursue a career in mountain guiding and moved to Bishop after unintentionally falling head over heels for the Eastern Sierra during a weekend trip. He improved his skill sets as a client of fellow SMC guides Tyler Logan and Louie Allen before earning professional certification from the AMGA and NOLS to begin working as a guide/instructor in 2023. He is proud to now be in the position to call them both colleagues and also help others achieve their goals or experience the outdoors in more meaningful ways. His first love is to climb in the alpine regardless of the medium (rock, snow, or ice), though be assured, he isn’t picky and believes strongly that any day spent outside, no matter the activity or difficulty, is better than a day spent indoors.

Beyond the Eastern Sierra, he teaches three to four multi-week NOLS backpacking and rock climbing courses per year across various locations in Alaska, Wyoming, Utah, and Nevada. When not guiding/instructing anywhere, he works as the Online Sales Manager for Eastside Sports in Bishop, CA; actively serves on the Inyo County Search & Rescue team which covers missions everywhere from Death Valley to Mt Whitney; and, conducts ~6 weeks of reserve duty with the Marine Corps each year.

Allen Giernet grew up in San Diego and always had a thirst for the outdoors. Whether in the mountains, the ocean, or the desert – he had to be outside. After several years running the youth snowboard competition team at Mountain High, his longing to get into the peaks beyond the resorts took him into splitboarding. This in turn took him into the Sierras, The Rockies, The Cascades, and more. In 2010, he began teaching rock climbing as an AMGA Single Pitch Instructor in Joshua Tree and other So Cal Areas. In 2012, he founded So Cal Snow Avalanche Center, began teaching avalanche courses with the National Ski Patrol, and began to guide on splitboard. 

  He has traveled all over the west and beyond in search of great climbing and big snow covered mountains to find powder filled descents. But the magical Eastern Sierra will always hold a special place in his heart. 

  Allen currently calls Methow, Washington home in the North Cascades and still spends time in So Cal. He ski guides and teaches avalanche courses in The Eastern Sierra, Colorado, and the North Cascades. That thirst for the outdoors remains unquenched and Allen loves to share this enthusiasm with anyone and everyone out there. When not out in the mountains searching for the next descent, hiking, biking or paddling, he may be found running The Methow Store with his partner in the Methow Valley. Serving up cold beer and great food next to the best put in on the Methow River.

An enthusiasm for backpacking was Ian’s gateway into the mountains and soon led to a love of climbing. After cutting his teeth on the rock and ice crags of New England he traveled all over the country making ascents of everything from short roadside rock climbs to big peaks in remote areas. Over a decade ago he discovered that the Eastern Sierra hold a magical mix of amazing mountains and climbing, easy access, and good weather. Now this place is home for him and his family.

Though he loves all kinds of climbing, big walls and winter routes hold a special place in Ian’s heart. He rounds out the year with forays to Alaska, Red Rocks, Joshua Tree, Moab, the North Cascades, and Canada.

Larry is a native of the New Jersey shore. Raised as an ocean lover, Larry spent his early days surfing and being in the water as much as he could. Through an active involvement in scouting, as well as an adventurous friend group, Larry found a passion for the mountains. Naturally, this passion had him trade his surfboard for a snowboard, and he went west! Larry graduated from the University of Colorado Boulder with degrees in Environmental Studies as well as Atmospheric and Oceanic Circulation. In Colorado, he fell more in love with the mountains. After graduating, Larry moved to Alaska to explore the wilderness of the last frontier through backpack and canoe guiding. When COVID struck and found Larry abroad in Central America, he came back to the states hoping to get back to Alaska, but discovered the Sierra along the way. And the high peaks and the fairer climate of California was as far as he made it. Larry now resides here in Bishop, where he spends his time exploring the mountains via roped climbing, splitboarding, and hiking. When not guiding, Larry enjoys traveling and climbing the high, glaciated peaks of Central and South America. Larry’s favorite trip to lead in the Sierra is the Bishop to Mammoth backpack as the variety of the terrain offers tremendous opportunities for natural and human history studies! Larry holds a certification as a Wilderness First Responder, a Leave No Trace Trainer, and a AIARE Level I.

Anouk grew up on the glaciers and peaks of Switzerland where her family is from and currently resides. Anouk has had an appreciation for the elevated outdoors from an early age. She has lived in Europe, America’s east coast, and finally, she came to the west coast in her teens, and never left. Even though she calls the Eastern Sierra her home, she began her guiding career in the Pacific Northwest, where she worked on glaciated peaks such as Mt Rainier and Mt Baker, and rock guided during the summers. However, having learned to rock climb in California and frequenting the Eastern Sierra during her years living in Los Angeles, she ultimately returned to California eight years ago and has been guiding here year round. In the summers, Anouk guides rock and alpine trips, and during the winter seasons, she ski guides and teaches avalanche courses. She sees her guide work as a way to increase and infuse passion and knowledge into the outdoor community – her way of giving back after having been fortunate enough to receive solid mentorship during her initial years climbing in California.

Anouk became a Certified IFMGA Mountain Guide through the AMGA in 2025. She is also an AIARE avalanche course leader and AAI course leader.

Dave still remembers being 10 years old and seeing the face of Mt Yamnuska– a mile long rock face in the Canadian Rockies– and knowing that climbing would one day become his passion! A dual US-Canada citizen, he was born in Halifax, NS and moved to Calgary, AB in his formative years. He went to University in Calgary, receiving a bachelor’s degree in Ecotourism & Outdoor Leadership in 2007. It was a fateful day in 2013, on a road trip to Yosemite, that he drove over Tioga Pass and descended into the Eastern Sierra, discovering this special place. He was hired by the original owner, SP, in 2015, and has been guiding the trails and mountains of the Sierra Nevada ever since.

Dave continues to spend his winters in Canada, where he works as a Lead Guide and Guiding Manager at a heli-ski operation. In 2025, he became the Guide Manager at SMC.
