Snow Observation & Stability Analysis
Avalanche Education Course

The next step towards self-sufficiency in the mountains! Our AIARE Level II is a three-day/24-hour course that provides backcountry travelers an opportunity to advance their decision-making skills in more complicated situations such as being a leader within a small travel group, traveling in more complicated terrain, and/or developing a travel plan where resources are scarce.

Our AIARE Level 2 builds on the introductory avalanche hazard management model introduced in the AIARE Level 1 and adds to it the evaluation of critical hazard assessment factors. Students will describe and discuss the weather, snowpack, and avalanche processes and identify how they relate to observations and travel within avalanche terrain.

  • Who’s it for? Experienced backcountry travelers who are looking to expand their decision-making skills needed to lead a small group. – skiers, snowshoers, climbers, or snowmobilers.
  • How we go? Participants may take this course on backcountry skis, split board, or snowshoes.
  • Where do we go? Most courses utilize terrain on or near Mt. Washington and the northern Presidential Range.
  • Why go with AMG? Acadia Mountain Guides is New England’s original and most experienced AIARE provider and is led by IFMGA Mountain Guide Jon Tierney. Our curriculum meets and exceeds the AIARE Level 2 curriculum standards.
  • Pre-requisites:
    • Fitness, clothing, and equipment to ski or hike up to 8 miles round trip with a 10-pound pack. If skiing or riding, you should be advanced enough to ski ungroomed terrain at major northeast ski resorts.
    • An AIARE 1 Course (strongly recommended) or equivalent Level 1 training is required.
    • A winter of practical experience after the Level 1 course is highly recommended.
    • AIARE or AAA approved one-day Avalanche Rescue Course

Starting with an in-person classroom session, you will be lead through a review of AIARE Level I material, and we will take a look into your avalanche records of past seasons with the help of your instructor; the review consists of the following topics; what creates an avalanche-prone slope, where they may occur, red flag snowpack and weather observations, how to interpret and work with the “human factor,” and elements of preparation and tour planning. We will then build on these skills and learn about making in-depth weather observations in the field and at basecamp and how these observations correlate to our snowpackFrom there, we will head outside onto the snow to begin working on building snow profiles, making on the go “quick pit” observations, assessing snowpack layers and interphases, performing snowpack tests and documenting pit results, and how to manage risk in small groups. The final day will consist of a longer tour focused on building and executing a safe and fun tour plan, proper group travel techniques, decision making as a small team in the backcountry, how to manage risk in the field, and finally round out the course with an extensive debrief as well as how to communicate/submit your observations to other travelers and local avalanche experts. Throughout the course, you will have the opportunity to “pick the brain” of guides who have spent many years skiing and climbing in the mountains all over the world.

You will often find our instructors down the road at locally/skier owned SAaLT Pub enjoying locally sourced food and drink for dinner after a long day in the mountains!

We encourage you to join us there! We are delighted to continue conversing about snow, mountains, and more even after the class has ended!

No one starts the day expecting to get hurt in the backcountry. However, despite all we know and all we do, accidents can still happen. At AMG, we take your medical care seriously. Like many guide services, our leaders are trained as Wilderness First Responders; many are WEMTs. Additionally, all our regular employees participate in periodic medical skills review with our owner Jon who is a flight paramedic and lead instructor in wilderness medicine. Additionally, on courses traveling to remote areas such as Katahdin, Chic-Chocs, or Mount Washington, you can expect our guides to have pain and sedation medications available if needed.

AIARE courses are recognized across the country and are consistent with the international standards and recording methods. AIARE instructors participate in annual training and network continuously with each other to learn about the latest information in avalanche science. Courses flow sequentially regardless of where you take your class. AIARE courses teach you a way of thinking about snow travel rather than a protocol-based approach to learning. Save lives through education.

Please complete the following as pre-course work and be prepared to discuss in class.

On line learning:  Regardless of whether you are taking our Online Session or  not, The AIARE online learning component is great for getting a basic understanding of avalanche terrain, avalanche problems, and how to recognize suspect areas.  We strongly suggest looking at this in advance. Plan about 2 – 3 hours to work on the online content ahead of the class.

Download and begin reviewing The AIARE 1 Student Manual

Case Studies:

  • If you are a skier/boarder, please read the Tunnel Creek Avalanche case study.
  • If you are a climber or hiker, please look over the local case study from Tuckerman Ravine.
  • Be prepared to chat the case studies:  What went wrong, could you see yourself making similar decisions, what may have changed the outcome?

Tour Planning:

  • Tour planning is how you prepare to go into the backcountry.
  • A tour plan is generated by using the avalanche bulletin, combined with maps (both hard copy and electronic versions) and a weather forecast to understand how the weather will influence your plan.
  • It is easy to create reliable computer/phone-based tour plans to bring to the backcountry. You should always have a hard map and compass.
  • Your tour plan should give you an idea of the vertical gain, the distance, compass bearings, run options, areas to be careful of. Attached is a sample tour plan template.
  • Electronic tour planning is great, but you need to understand some basics as well. We will review tour planning basics in class but keep in mind it is not a navigation class. Please bring a compass, ideally with a base plate.
  • We will be doing some sample tour planning during the course. It is helpful if you are able to bring a laptop computer.
  • We suggest downloading the following programs and apps which are useful for digital mapping:

To your laptop: Caltopo
To your smartphone: the mapping apps Avensa, Caltopo, Gaia, and Windy for weather.

         Tour planning resources:

We seek to find the best snow and learning conditions possible for each course and to provide different venues for each field day. If we travel to the west side of Mount Washington a nominal parking fee may be charged at the Cog Railway base station parking area. Occasionally we utilize lift access at Wildcat to access terrain and this may require purchasing a single ride lift pass.

Staying Alive in Avalanche Terrain, 3rd Edition. Bruce Tremper

  • This edition features a wholly new chapter in which Bruce pulls all the pieces together to create an organized, step-by-step system for making decisions off, and on, the mountain.

Avalanche Essentials: A Step-by-Step System for Safety & Survival, Bruce Tremper

  • This is the companion to Staying Alive in Avalanche Terrain the bestselling avalanche text in the U.S – with easy-to-understand safety tips and checklists to help anyone stay safer in avalanche terrain. It is a small, take-along resource to reference in the field and assist decision making. Winter athletes don’t necessarily want to be snow scientists but playing in avalanche country does require basic knowledge of the risks in order to stay safe.

Thinking, Fast and Slow, Daniel Kahneman

  • This book explores the ways we think and make decisions under pressure, we find it valuable as we are exploring the idea of leading a group or being an active part of the decision making in the backcountry.

Dragons in the Snow, Edward Power

  • This book based around the main character Craig Gordon (lead forecaster for Utah Avalanche Center) explores the complex science behind avalanche forecasting and rescue.

Snow, Weather, and Avalanches: Observational Guidelines for Avalanche Programs. (SWAG)

Enjoying the outdoors necessitates a certain degree of risk-taking. You are participating in this trip and entering the winter backcountry environment at your own risk.  You are choosing to engage in an activity in which participants have been injured and killed. While such accidents are rare, they may occur at any time and be out of our control. Our guides draw upon solid guide education coupled with extensive experience to manage significant hazards inherent to mountain travel.  Some of the hazards that can lead to injury or death associated with this trip include but are not limited to extreme weather, demanding physical travel, avalanche, vehicle transportation, and falls or collisions while skiing or snowboarding. Please be sure that you are fully aware of such risks. It is our goal to interpret the environmental, situational, and group variables and to make educated decisions to minimize dangers to you while at the same time providing an enjoyable and memorable experience. 


Self-reliance in the face of adversity is expected on the part of the wilderness traveler entering the wilderness. Rescue is not automatic. For all practical purposes, our party is alone and must depend upon our own resources for self-rescue and be equipped for an extended emergency. Cellular phones and radios should not be relied upon in an emergency.  


Finally, this is a group trip and good expedition behavior is critical. Participants are asked to stay with the group until everyone has safely exited the backcountry. 

A 100% deposit is required for registration.

The goals and objectives of this program are to learn avalanche skills. It is unlikely that we will pursue any summits during the course. Commonly we ascend into areas around Tuckerman Ravine, Gulf of Slide, and ravines adjacent to the cog railway. We will make every reasonable effort to reach these areas, however, extreme weather, avalanche conditions, inadequate personal fitness, difficult terrain, or park weather/travel closures may make it impossible to achieve our desired terrain objectives.

People often ask if it’s appropriate to tip the instructor. Tipping is never expected but always greatly appreciated.

This is your course. The more you let your instructor know what your needs are, the more he or she can help you. If you don’t understand, ask questions. If you have special interests, let your instructor know. If your instructor has provided you with a great experience and shared his or her knowledge and joy of the mountain world with you, a thank-you note or gratuity is always well received. If they have not, we would like to know about it.

A minimum of four (4) participants are needed to run this program and there is a maximum of twelve (12). The decision to run the program will be made three weeks prior to the start date. In the case of low registration, you will have the option of joining another trip, receiving a refund, or possibly paying an additional amount to allow the trip to run with low numbers.

Are you part of a college organization, ski club, etc.? We are happy to schedule a customized course for organizations, small groups, and individuals through New England and Eastern Canada. Of course, if you would like to schedule a course or trip to Iceland, Colorado, or Japan, etc. we would be very pleased to work with you.

Acadia Mountain Guides Climbing School is certified through the American Mountain Guide Association and the Professional Climbing Instructor Association. Acadia Mountain Guides actively supports furthering their guide’s development throughout their career. That means our guides are constantly taking steps to progress their skills and will provide you with an exceptional experience. AMG is also a proponent of helping clients reach their goals, whether its having an epic day in the mountains or gaining skills to get into other terrain, Acadia Mountain Guides Climbing School can get you there!

Our instructor team is the strongest in New England and our courses reflect that. We were at the table early on when the concept of furthering public avalanche education in the U.S. was being discussed and the American Institute for Avalanche Research and Education was being created. For several years we were the only climbing school sponsoring AIARE avalanche courses in the eastern U.S. We often ran them at a financial loss, brought avalanche guru Karl Klassen (Canadian IFMGA guide, chief forecaster for the Canadian Avalanche Association, and initial technical director for AIARE) in from western Canada to teach them, and corralled all of our friends to attend just to have enough people to run the course. In fact, many of the snow rangers and current avalanche course providers who are working or have worked on Mount Washington were participants in those early courses. Today, times have changed and the demand for courses has created an abundance of courses and providers. While all the courses are good, we believe ours to often be superior because of the strength of our team.
