1. Concentration claim
In backcountry trouble, fatigue on the way down, not being found, and wet cold account for the calls, while fire toys and long-term bushcraft fill the pack.
2. Hard anchors
- Welter, Sholl, Strout, and Woodard, Wilderness & Environmental Medicine, 2015. https://pubmed.ncbi.nlm.nih.gov/26476846/. Baxter State Park, July 1992-June 2014. 754 incidents. Trauma 51%. Late or lost 30%. Slips or falls 67% of injuries. Lower extremity 31%. When applicable, 84.4% of acute need was on descent. Fatigue causative in 66% of medical SAR events. Mean age 38.9; fatigue as the primary complaint 48.7. 60.5% male. 19 fatalities.
- Baxter State Park plain-language summary of that work. https://baxterstatepark.org/wp-content/uploads/2017/05/SAR-Analysis-Review-1.pdf. About 20% of all SAR responses were fatigue, and 66% of medical responses. Different denominator from the paper's 66% of medical events.
- Heggie and Heggie, Journal of Travel Medicine, 2009. https://pubmed.ncbi.nlm.nih.gov/19192124/. NPS units, 2003-2006. 12,337 SAR operations, 15,537 visitors, 522 fatalities. 40% of operations on Saturday and Sunday. Ages 20-29: 23%. Males 66.3%. Activities with the most operations: day hiking, motorized boating, swimming, overnight hiking, nonmotorized boating. Vast majority located within 24 hours. Most common contributing factors, with no shares printed in the abstract: error in judgment, fatigue and physical condition, insufficient equipment, clothing, and experience.
- NPS Ten Essentials. https://www.nps.gov/articles/10essentials.htm. Tell someone the route and the return time. Extra clothing for the worst conditions; bright layers so searchers can see you. Shelter called one of the most important elements in an emergency. Drink before you are thirsty; carry water and treatment. Fire is a signal and a heat source; follow park fire rules. List from The Mountaineers, Freedom of the Hills, 8th ed., 2010.
- Sequoia and Kings Canyon trail safety. https://www.nps.gov/seki/planyourvisit/trail-safety.htm. Wet clothes can lose up to 90% of their insulating value. Hypothermia can develop in cool air as high as 60°F (16°C), or in water. Stay dry. If you cannot carry all your water, you must treat it. Do not copy a treatment recipe into the article.
2b. Field 80/20 examples
| Approx % claim | Field / context | Source | Where it will sit |
|---|---|---|---|
| Up to 90% of insulating value lost when clothes are wet | Park safety page, not a lab paper | NPS Sequoia | Dry section |
| 66% of medical SAR events; about 20% of all responses | Baxter fatigue, two denominators | Welter 2015 and park summary | Descent section and misreads |
| 84.4% of acute need on descent, when direction was noted | Baxter | Welter 2015 | Descent section |
| Intro 20% / 80% | Rule of thumb for the pack | hedge | Intro |
3. Original observation
A four-line card before any new tool: who knows the route and the call-in time, a layer or shelter that still works if wet, water already in the pack, a turn-around time set for the way down.
How it becomes a section: "Four lines, then no new gadget."
4. Ignored majority
Extra fire starters, blades, month-in-the-woods courses, while the Saturday day hike is the incident the national-park file actually sees. Household gallons belong to prepping, not this slug.
5. Composite policy
| Scenario | Keep as Illustrative? | Cut instead? |
|---|---|---|
| Ferro rod, cotton hoodie, no one expecting a call | Yes |
6. Vital few
- Turn around while you can still walk
- A person at home who knows the route and the time
- Stay dry (layer or shelter you have opened)
- Water already in the pack
7. Device budget
Template C. Pattern, ignored pile, warning, and one action on the bottlenecks. One 8020 move. No viz. No purification recipe.
7b. Viz & misreads
Viz: none.
Misreads: 20% of all calls is not 66% of medical calls; the climb is not where Baxter's noted injuries clustered; a course does not replace the person at home.

9. Sign-off
- ☑ Brief complete
- ☑ No invented "20% of skills cover 80% of survival situations"
- ☑ Not a medical or fire-making manual
