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.

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.

Certifications and professional courses include:

  • AMGA Certified Rock Guide
  • AMGA Aspirant Alpine Guide
  • AMGA Assistant Ski Guide
  • AIARE Level 1 Instructor

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.

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.
