About the Everest Region Archive
The Everest region, the Khumbu, is far more than the mountain itself. It is the airstrip at Lukla, the trading town of Namche Bazaar, the monastery at Tengboche, a string of lodges up to Gorak Shep, the base camp on the Khumbu Glacier and the camps above it. Most of what happens there never reaches the international news: a porter’s evacuation, a new rule from the rural municipality, a flood that takes out a bridge. This Log keeps all of it in one dated, searchable place.
It covers two kinds of events. The first is incidents: climbing and trekking accidents, avalanches, aviation crashes, floods and the rescues that follow them. The second is change: permit fees, waste and safety regulations, infrastructure, and connectivity such as mobile data and Wi-Fi at base camp. Both shape what a season in the Khumbu is like, so both belong in the record.

How each entry is built
Every event gets its own dated entry on this Log’s timeline. The entry date is the date the event happened, not the date it was written up, so the timeline reads as history even when an old event is added years later. Each entry opens with the same fact table: event date, location, type, impact (deaths, injuries, missing, displaced where relevant), verification status and current status. The write-up follows, then the sources it was built from.
Event types used here: climbing accident, avalanche or storm, trekking accident, aviation or helicopter incident, missing persons, earthquake or flood, rescue and evacuation, infrastructure and connectivity, regulation and permits, environment and waste, and major historical events.
Verification levels
- Unverified: early reports only; details likely to change.
- Partially verified: at least one credible source confirms the event, but key details (names, numbers) are incomplete or disputed.
- Verified: confirmed by an official body or by several independent, reliable outlets.
When figures differ between sources, which is common for death tolls in the first days after a disaster, the entry says who reported which number instead of quietly picking one. When new information emerges, the original entry gets a Correction or Source note attached to it rather than being rewritten, so the record of what was known and when stays intact.
Sourcing and originality
Entries are written from notes, in Merolog’s own words, after reading at least two independent sources. Direct quotes are short, in quotation marks and credited. Photographs come only from freely licensed collections such as Wikimedia Commons, with the photographer and licence named under each image; news agency photos are never copied. Preferred sources are official bodies (Nepal’s Department of Tourism, Nepal Police, the government’s aircraft accident investigation commissions, ICIMOD, conservation-area offices and local municipalities), established Nepali outlets (The Kathmandu Post, The Himalayan Times) and specialist mountaineering reporting (Explorersweb, Alan Arnette, the American Alpine Club).
