After-Action Review: Learning from Every Expedition

By a Senior Climbing & Wilderness Survival Expert with 20+ Years of Field Experience


Introduction: The Summit Is Not the End

Many climbers think the expedition ends when you leave the mountain — but the real growth begins after you’re home, unpacked, and reflecting. Whether you reached the summit or had to turn back, every expedition is a classroom, and the “after-action review” (AAR) is your final exam.

In elite military and rescue units, AARs are non-negotiable. As a high-altitude guide and survival instructor, I’ve adopted this ritual after every trip — from technical alpine ascents in the Dolomites to multi-week expeditions through Andean cloud forests.


1. What Is an After-Action Review (AAR)?

A structured, honest analysis of your expedition — what worked, what didn’t, and how you’ll improve next time.

3 Core Questions:

  1. What was planned?
  2. What actually happened?
  3. Why was there a difference — and what can we learn from it?

“You either win, or you learn. If you do both — even better.”


2. Why Every Climber (and Team) Needs an AAR

Even experienced mountaineers make mistakes. What separates amateurs from pros isn’t perfection — it’s the ability to self-correct.

Benefits of a Proper AAR:

  • Identify gaps in planning or gear
  • Reinforce best practices
  • Prevent repeat errors
  • Improve team dynamics
  • Develop self-awareness and decision-making under stress

3. How to Run an Effective AAR

✅ Do It Within 72 Hours

Fresh memories = accurate insight. I recommend doing the first review right after returning, while emotions and details are still raw.

✅ Be Honest, Not Harsh

Create a judgment-free zone. No blaming. Everyone contributes. The goal is improvement, not ego.

✅ Involve the Whole Team

Each climber notices different things. A porter might highlight terrain risks that the lead missed. The medic might point out altitude issues the group ignored.

✅ Write It Down

Always document key takeaways. I keep a separate AAR logbook — it’s become one of the most valuable training tools I’ve ever built.


4. Key Areas to Review

Here’s a checklist I’ve refined over two decades and 100+ expeditions:

🧭 Planning & Logistics

  • Was the route realistic for team skill level?
  • Was contingency time/weather accounted for?
  • Any border, permit, or travel issues?

🧗‍♂️ Technical Execution

  • Did we use proper climbing techniques?
  • Were transitions smooth (belays, glacier travel, rope management)?
  • Gear failure or mismanagement?

⛑ Health & Safety

  • Any injuries, near misses, or AMS symptoms?
  • Was emergency response adequate?
  • First aid gear sufficient?

🧠 Team Dynamics

  • Was communication clear, especially under stress?
  • Any friction or leadership issues?
  • Was morale sustained?

🎒 Gear & Equipment

  • What worked flawlessly?
  • What failed or was unnecessary?
  • What do we upgrade/replace?

🏕 Environmental & Ethical Practices

  • Did we leave no trace?
  • Respect local communities/land use?
  • Waste properly managed?

6. Solo Climbers: Do a Self-Debrief

Even if you climb solo, review is crucial. Ask yourself:

  • Did I overextend anywhere?
  • What decisions felt rushed or emotional?
  • Where did I perform strongest?

I often record a voice memo right after a climb. Raw, unfiltered — then I listen again a week later. That’s where real insight lives.


7. Turning Lessons into Action

Learning is only valuable if applied. After every AAR:

  • Update your gear checklist
  • Adjust your training plan
  • Create a short summary of “Top 3 Lessons”
    (I tape these into my gear box as a reminder before the next trip)

8. Final Thoughts: Good Climbers Learn from Experience, Great Ones Learn from Reflection

Mountains don’t reward memory — they reward adaptation.

The AAR process is how we evolve.
It’s how a trip that didn’t go as planned can become the foundation for the one that finally does.

So after every expedition, ask yourself:

“What did this mountain teach me?”

And then write it down. Study it. Share it.
Because the climb continues — long after the summit.
