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:
- What was planned?
- What actually happened?
- 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?
5. Sample AAR Snapshot (Real Expedition – Andes 2019)
| Category | Observation | Lesson |
|---|---|---|
| Weather planning | Underestimated 2-day storm window | Add satellite updates + extra buffer |
| Water purification | 2 filters clogged by Day 5 | Carry backup chlorine tabs |
| Team conflict | Disagreement on turnaround decision at 5,100m | Establish clearer summit cutoff in pre-brief |
| Successes | No altitude issues; excellent camp hygiene | Maintain hydration + gradual acclimatization pacing |
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.
