   Tính toán

   Forrester and Holstege analysed 5 years of Shenandoah National Park ranger case-reports (2003 to 2007). The 2.7 per 100,000 figure is the rate at which a park visitor is sufficiently injured or ill to be formally recorded by a ranger — a sampling floor, not a per-day injury rate. Most blisters, minor sprains, and even some moderate strains never reach a ranger; the figure is best read as "rate of ranger-attention-level events per park visit." Because not every park visit is a hike, the per-hike rate is meaningfully higher than the per-visit rate quoted here — we use this source primarily to anchor the lower bound of the injury severity ladder, not the headline native rate. The finding that distal lower-extremity soft tissue injury (ankle sprain, knee strain) dominates is consistent across every hiking injury study and drives the personal factor multipliers.

   Independent dataset (Shenandoah ranger case-reports). Does not overlap with NOLS expedition data or NPS-wide SAR aggregates.

   Tính toán

   The NOLS injury rate is the cleanest per-day measure in the wilderness-medicine literature, but NOLS program-days are multi-day expeditions with packs, often off-trail, and student populations skewed young and adventurous. They are an upper-bound proxy for recreational day-hiking on maintained trails. We divide the NOLS rate by approximately three to land the per-hike-day medically- attended-injury rate near 1 in 2,500 — the value used as native.numerator/ denominator. The factor of three is a defensible mid-range adjustment: NOLS participants carry packs, hike off-trail, and accumulate continuous exposure across multi-week expeditions, all of which roughly triple injury risk per day relative to a four-hour Saturday day-hike on a Class 1 trail with no pack. The factor is the largest source of uncertainty in the entry's headline, reflected in the wide normalized.uncertainty band of 0.10 to 0.35.

   Độc lập

   Independent of all NPS-based sources. Same data lineage as Leemon and Schimelpfenig 2003 (1.07 per 1,000 program-days for 1999 to 2002) but a different time-window, not double-counting.

   Tính toán

   NPS-wide SAR totals over 16 years. 24,288 ill or injured divided by 16 years equals roughly 1,520 SAR-attended injuries per year. NPS visitation in this window averaged about 280 million visits per year, so the SAR-injured rate is roughly 5.4 per million visits and the long-run fatality rate roughly 0.6 per million visits. Lane et al. 2015's modern NPS fatality counts (an annual average of about 250 deaths across ~280 million visits, or roughly 0.9 per million) are the same order of magnitude, so the all-visit fatality rate is on the order of 0.6 to 0.9 per million park visits. Not every park visit is a hike, so the per-hike-day fatality rate is somewhat higher than the all-visit rate but remains on the order of one per one to a few million hike-days. Over a 600-hike career, a per-hike-day fatality rate of roughly 1.7e-7 to 5.5e-7 compounds to a lifetime fatality probability of about 1 in 3,000 to 1 in 10,000, comparable to the lifetime probability of dying in a bicycle crash. This source supplies the SAR severity rung directly (5.4 per million NPS visits) and the long-run fatality floor (0.6 per million visits); the modern Lane counts corroborate the same order of magnitude.

   Shares the NPS-IRMA incident database with Lane et al. 2015. The Heggie and Lane numbers should not be arithmetically combined; both summarise the same reporting system at different points in time.

   The modern (post-2010) per-visit EMS denominator. An EMS-call rate of roughly 37 per million NPS visits is broader than SAR — it includes parking-lot cardiac events and motor-vehicle crashes in addition to wilderness incidents. For a hiking-specific subset, dividing by approximately three (hiking is one of several activity contributors that trigger EMS) gives roughly 12 per million hike-visits or 1 in 80,000 per hike-day. This is the same order of magnitude as the Heggie SAR-injured rate, providing a cross-check on the SAR severity rung. Lane also reports 262 total NPS fatalities in 2012 and 238 in 2013 — an annual average of roughly 250 deaths across about 280 million visits per year, or about 0.9 per million visits, consistent with the long-run Heggie figure of roughly 0.6 per million. (Note: the two years' totals are separate annual counts and must not be summed into a single year.)

   Same NPS reporting system as Heggie. Use Lane for the modern per-visit baseline and Heggie for the long historical aggregate; do not double-count.
