We feel strongly that training as well as experience is key to a guide’s development as a professional. We value the expertise that years of climbing and mountaineering has brought to our guiding but we also recognize that training and evaluation by peers are necessary before one can truly be called a “professional”. Therefore we require our guides to show a commitment to their profession by being involved in the American Mountain Guide’s Association courses and exams.

Our full lead guides are certified by the American Mountain Guides Association and our assistant guides are required to have taken an AMGA guides course and to have served a lengthy and rigorous apprenticeship under direct supervision of lead guides. We devote a significant portion of our gross each year to the training and professional development of our guides. This training includes sending our assistant guides to AMGA guide training courses, attending biannual medical training courses to maintain certificates, and being involved in the AMGA training process as examiners and instructors. If you compare our level of training and professionalism to other guide services we are confident that you will find our standards to be among the best.

Meet Our Guides

SMC is proud to be employing the talents of guides who are some of the most experienced professionals in mountain guiding. This list is not complete due to it being nearly impossible to catch guides standing still!

Tyler Logan

Tyler grew up hiking in the Sierra Nevada before being introduced to rock climbing as a teenager. Since that time, he has climbed extensively in this same mountain range, including Yosemite (he has climbed El Capitan multiple times) as well as various other crags and mountain ranges throughout the West. Much of this climbing happened during spring, summer and winter breaks while working as a high school English teacher in southern California. After more than ten years in the classroom, Tyler made a career change and began guiding in 2016. He loves being able to make use of his teaching background while working outdoors and helping people achieve their goals. While climbing is his first passion, Tyler also enjoys hiking, backcountry skiing, running, cycling, and a bit of fly fishing now and then. He lives in Bishop with his wife, Mona.

Tyler’s Certifications:
• AMGA Certified Rock Guide
• AMGA Apprentice Alpine Guide
• AIARE Instructor
• Wilderness First Responder

Michelle Wenski

Michelle is a backpacking and rock climbing guide certified as a Wilderness First Responder, AMGA Single Pitch Rock Instructor and AMGA Apprentice Rock Guide. Michelle grew up in southern California, but after falling in love with snowboarding at Mammoth Mountain, it did not take her long to leave the coastal lifestyle of surfing, organized sports and traffic for the mountain life. She has called now Mammoth Lakes her home for 15 years. You can find her hiking, trail running, mountain climbing, snowboarding, skiing, rock climbing, and adventuring with her dog and friends in her “big backyard,” the eastern Sierra Nevada.
After enjoying a decade of personal trips exploring the High Sierra, Michelle decided it was time to share that joy with others by guiding trips for SMC. Two of her favorite trips are the John Muir Trail and its cross country neighbor, the Sierra High Route. Nothing is better than escaping the fast-paced front country for weeks at a time to find solace in the back country. Day to day tasks at home are replaced by self-sufficient foot travel across hundreds of miles of alpine terrain where basic needs of food, water, shelter and rest become the priority. The only things on the to-do-list include seeking out: vistas, alpine lakes, high passes, open meadows, peaceful campsites and other hidden gems along the way.
Creating tasty backpacking meals is something Michelle enjoys. She has taken years of work alongside talented local chefs and applies it to her backcountry meals.

Larry Gumina

Larry, SMC Guide

Larry is a native of the New Jersey shore. Raised as an ocean lover, Larry spent many warm summer days, as well as frosty winter days surfing the Jersey swells. 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 wetsuit for a climbing rack, and he went west! Larry graduated from the University of Colorado Boulder with a degree in Environmental Studies and a minor in Atmospheric and Oceanic Circulation. In Colorado, he fell deeper in love with rock climbing, backpacking, and snowboarding. After graduating, Larry moved to Alaska to pursue summer backpack and canoe guiding. The winters were too dark for him, so he always fled to the sunnier states of the west coast during the winter months. Eventually, he found the Sierra, and fell in love with the high peaks and the fairer climate of California. After a few years of nomadic life, Larry now resides in South Lake Tahoe, where he spends his time rock climbing and tracking fresh powder runs on the many skin accessible peaks of the area. Larry’s favorite trip to lead in the Sierra is the Mammoth to Yosemite 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.

Ryan Huetter

ryan_huetterRyan grew up near the coastal tidewaters of the Puget Sound in Washington State, but has since traded moss and rain for the sunshine and splitter cracks of the Sierra Nevada.  Since graduating from Western Washington University in 2006 with a bachelor’s degree in Outdoor Adventure Management, Ryan has called the Sierra home. Beginning with leading extended backcountry mountaineering and backpacking trips for the Outward Bound School all over the range, he finally settled down in Mammoth Lakes to enjoy the unbelievable skiing and climbing the Eastside is famous for.

Ryan’s passion for climbing has taken him around the world, from Yosemite Valley where he has climbed more than 15 big walls including a 9 day ascent of Tribal Rite (5.10 A4), to 6 seasons in Patagonia where he has made many major ascents including Fitz Roy and first ascents of remote alpine walls.

But year after year, the Sierra Nevada remains Ryan’s base, and he loves introducing people to the Range of Light.  Ryan’s favorite Sierra climb is definitely the Third Pillar of Dana, of course coupled with fish tacos from the Mobil Station.

Calvin Tague

calvinCalvin grew up near the city of Boston and quickly realized his need to be in close contact with nature. He enrolled at Unity College of Maine in 2010, took a National Outdoor Leadership School semester course in 2011 and graduated in 2014 with a Bachelors of Science in Adventure Based Environmental Education. Shortly after, he moved to the Far East in search of adventure and professional experience. I Nepal, he worked as an educator and guide for Initiative Outdoor, a leadership school in Kathmandu. During his half a year stay he managed to help lead back packing expeditions as well as rock climbing and caving trips. Calvin taught children about the joys of outdoor living at local school and invited students to join him at the office for some bouldering sessions and climbing lessons. Next, Calvin made the decision to move to Vietnam where he worked as a rock climbing and sea kayak guide in Lan Ha bay. Another half a year was spent here exploring his new home island of Cat Ba and journeying into the bay to be the first to summit some of the karsts’ most inviting rock faces. Since Calvin’s travels in Asia he has returned home to the states only to continue his travels.  But since May of 2016 he has made a big change. He’s settled here on the eastside and dedicated himself to guiding in the Sierra Nevada and practicing the art of alpine climbing.

Joe Crawford

Joe began exploring the mountains while studying Economics at the University of Oregon. Sport climbing at Smith Rock and mountaineering on the Oregon Volcanoes soon gave way to a love of all mountain sports from bouldering to ice climbing and skiing. Drawn to California, for its superior weather and range, Joe began guiding on Mount Shasta in 2011 and in the Sierra in 2014. Having moved to the Eastern Sierra for the incredible alpine terrain, Joe couldn’t help but find a home in June Lake. Joe enjoys skiing the unheralded terrain of “the loop,” from the obvious classics on Carson Peak to the lesser known powder stashes of Fern Creek. In the summer months, he spends his off duty time climbing the alpine rock routes of the high country, his favorite thus far is the Direct North Buttress of Merriam Peak. When he’s not guiding and playing throughout the range, he can usually be found extolling its virtues in a local hot spring, rambling through the hills with his dog or perched at the local brewery.

  • AMGA Advanced Rock Guide Course
  • AMGA Ski Guide Course
  • AMGA Alpine Guide Course
  • Wilderness FIrst Responder
