| About our Mountain Guides
Acadia Mountain Guides Climbing School is a company of professional guides. Since our inception in 1993, we have encouraged formal training and evaluation of all our guides. Our guiding standards are among the best in the industry and represent the highest standards in Maine. Our guides are friendly, dedicated professionals whose talents lie in their technical expertise, climbing ability and their skill as educators. The quality of our guides is what makes Acadia Mountain Guides Climbing School your best source for climbing instruction.
Our school has been consistently accredited by American Mountain Guides Association (AMGA) since 1993. We required all of our guides to meet the terrain guidelines of the revised 2006 AMGA accreditation program. The revised accreditation standards differ from the past standards in that they require each individual guide to have experience, guide education and evaluation appropriate to the terrain they work on. In the past accreditation was a brief review of staffing, permits, field performance and insurance. However, of utmost importance to you are the training and experience of your personal guide who is the person tying into the other end of your rope!
Surprisingly, most U.S. guides have little formal guide education and only a handful are currently certified.
Our guides are veteran climbers with several years of diverse climbing experience. By requiring in specialized guide education courses we maximize competency and efficiency and greatly reduce risk. Our greater efficiency allows more time to teach you important skills, and to provide you with more climbing opportunities without feeling rushed. All are also certified at or above the Wilderness First Responder level of medical care. Our internal training keeps everyone up on the latest techniques and current on the best local practices. We are committed to providing you with the best climbing experience possible. It is our goal to provide a supportive climbing environment that maximizes your time and minimizes your risk. Our mission leads us to continually develop cutting edge ideas and techniques that improve the delivery of our instruction. Many of these ideas have become the foundation guide training. We believe that the guiding art requires extensive climbing experience and a multi-faceted educational background. We take our philosophy to heart and work to promote responsible climbing and wilderness use as well as responsible guiding on both a local and national level. We are proud to be participating in the development of professional standards that other guide services aspire to. Simply put, we are attentive to the details. We look forward to sharing our love of high places with you and invite you to take a look at our backgrounds.

SILAS ROSSI
AMGA Certified Rock Guide
Registered Maine Guide, Recreation
|
|
Silas is one of approximately 150 AMGA Certified Rock Guides in the United States and is passionately pursuing his goal of becoming
an internationally licensed IFMGA (International Federation of Mountain Guides Association) mountain guide.
His natural affinity for the great outdoors developed into a lifetime commitment to mountaineering in the late 90's at the University of Maine, when Jon Tierney, an IFMGA licensed mountain guide, introduced Rossi to climbing. While majoring in Parks, Recreation and Tourism, Rossi quickly recognized the benefit of professional guide training. He soon began guiding student trips and later joined the Acadia Mountain Guides team in 2001.
While there are fewer than 60 guides in the US that have achieved IFMGA status Rossi is well on his way to this remarkable distinction at only 27. An active member of the AMGA and PCIA, Rossi strives to be on the cutting edge of guiding techniques and practices.
Rossi is committed to constantly improving himself as a guide and aims to offer the most
rewarding experience possible to his clients.
“My goal is to provide adventurous people with new life experiences,” he says, “helping
them push their limits both mentally and physically while effectively managing potential
hazards. While there is inherent risk involved in climbing, a professionally trained guide
can minimize that risk while providing an environment that is conducive to learning.
Many people first begin climbing with friends, but will certainly learn the correct way to
do things more quickly, and more safely, with someone who has invested in professional
training and has broad experience to draw from.”
He has also guided in many of the rock and ice climbing areas throughout the Northeastern US, and has led groups to several high altitude peaks in Ecuador (including Illiniza Norte, Cayambe, Cotopaxi and Chimborazo). He has led mountaineering trips in the Northern Cascades and guided alpine rock routes in the High Sierra. Rossi has also enjoyed many personal trips to some of the premier climbing destinations throughout the U.S. He has explored the miles of white granite in the High Sierra, the glaciated peaks of the Northern Cascades, the endless vertical ice of
the Canadian Rockies, and as well as some of the extraordinary alpine terrain of the
Central Alaska Range.
Rossi’s most memorable adventures include those on Mount Rainier's Liberty Ridge;
Dark Star of Temple Crag, Resolution Arete in Red Rock; the infamous Terminator of
Alberta, Canada; and in early 2007, four Lake Willoughby ice routes in a day, including
Who's Who in Outer Space, The Last Gentleman, The Promenade, and Twenty Below Zero Gully. Just this spring, he and a fellow guide made a 44 hour camp-to-camp push on the 4,000 foot wall of the Moonflower Buttress on Mount Hunter in Alaska. Always
thinking ahead to the next big adventure, Rossi is currently putting together plans to
explore the jagged peaks of the French and Swiss Alps.

RYAN CAMPBELL
AMGA Rock Instructor Course
PC IA Single Pitch Instructor
AMGA Top Rope Site Manager |

Ryan grew up in Denver, Colorado but did not find his passion for rock climbing until attending Dixie State College in southern Utah. He began guiding in 2004 for the Auraria Campus Outdoor Adventure program in Denver, CO that serves the three institutions on that campus (Metropolitan State College of Denver, University of Colorado Denver, and the Community College of Denver). After completing his BA at Metro in Tourism Operations he continued on to pursue his Masters degree from UCD in their Information and Learning Technology program and continued working with the Adventure program as a graduate assistant to the director. After completing his masters in December he hopes to work as an instructor for the Recreation Professions department at Metro State.
Ryan's first love is rock climbing, but has also guided ice climbing and canyoneering multi-day trips. From learning to climb in local indoor gyms, Ryan now sets his sights on longer and longer trad routes. With Colorado's front range in his back yard, he has honed his rock skills on some of the most classic lines in the western US; from Eldorado Canyon, to the South Platte, Flatirons, Boulder Canyon, and frequent trips to the Utah desert.

Peter excels on steep ice but is equally at home on hard rock climbs and steep ski descents. He has climbed extensively in New England and traveled to many of the climbing and mountaineering hotspots in the western U.S and Canada as well as the Dolomites in Italy. Peter has notable ascents of routes ice routes such as Polar Circus and the Weeping Wall in Canada and, along with fellow AMGCS guides Craig Luebben and Jon Tierney, established several first ascent ice climbs in western China in 2001. Peter has also guided several ascents of high altitude peaks in Ecuador including Cotopaxi, Cayambe, Illiniza Sur and Antisana.
During the past year, Peter spent much of his time between guiding climbing and skiing in the western U.S. completing several noteworthy ascents including: Mount Rainier's challenging Liberty Ridge, Liberty Bell Crack, Mt. Shuksan, Forbidden Peak and Mt. Stuart in the Cascades; South Face Washington Column, Regular Northwest Face of Half Dome in a single day, and the East Buttress of El Capitan in Yosemite National Park; and Journey Home IV in Colorado's Black Canyon.
