State of Mountaineering 2026: Trends, Data & Analysis
A research-based review of global climbing: government permit structures, summit outcomes, mountain fatality metrics and emerging environmental change.
The report synthesizes published datasets and expert/authority materials. Its own methodology identifies estimates and limitations—read the source before reproducing a figure.

Mountaineering Statistics 2026: Death Rates, Success & Risk
A citable starting point for mountain fatality records, summit-success comparisons and long-term risk trends. Every headline statistic should lead readers to its dated source and denominator.

Mountaineering’s Worst Decades: Deaths vs Risk
A decade-by-decade comparison of deaths, expedition participation and normalized risk in the Himalayan Database. Explains why the decade with the most fatalities is not necessarily the most dangerous per climber.

Mountaineering Deaths by Decade: Are Mountains Getting Safer?
A long-view investigation of mountaineering risk and the changing relationship between participation, fatalities and survival outcomes, with emphasis on source scope and comparability.

Why Kilimanjaro Climbers Fail: Lessons From 2,000 Trip Reports
An investigation into summit-day failure patterns on Kilimanjaro, including route choice, itinerary length, altitude acclimatization and decision-making near the summit.

Why Climbers Die on Everest Summit Day: 500 Reports Analyzed
Examines reported patterns involving timing, oxygen, fatigue, weather, descent decisions and the severe limits of rescue above 8,000 metres. Read the investigation for evidence and limitations.

Mountaineering Operator Power Rankings 2026
A 40-operator comparison based on six publicly verifiable transparency and accountability signals, arranged into four editorial tiers. It is not a guarantee of operator safety or a substitute for individual due diligence.

GSG studies may be quoted with visible attribution, a link to the original research and an accurate description of the source data. Please do not present compiled estimates as audited national totals.
- 1. Link to the specific study. Each report card has a permanent original-article URL.
- 2. State the year, scope and denominator. Especially for death rates, summit success and cost comparisons.
- 3. Use context, not just the bar chart. “Deaths per summit” is not the probability of death for an individual climber.
- 4. Credit the source visibly. Editorial attribution is welcome; a followed link is not a required condition.
