Geologic Context

• Formed by Indian Plate colliding with Eurasian Plate (~50 Ma, ongoing)
• Still rising ~5 mm/year
• Karakoram = distinct range (more glaciated, steeper)
• 14 "eight-thousanders" total (3 more: Gasherbrum II, Broad Peak, Shishapangma)

Notable Non-Himalayan High Peaks

• Aconcagua (6,961 m) — Andes, Argentina (highest outside Asia)
• Denali (6,190 m) — Alaska Range, USA
• Kilimanjaro (5,895 m) — Tanzania (highest free-standing)
• Elbrus (5,642 m) — Caucasus, Russia (highest in Europe)

Climbing Reality

• All 8,000ers require permits, logistics, acclimatization
• Commercial expeditions: $30k–$100k+ (Everest)
• Death rates: Annapurna I ~27%, K2 ~23%, Everest ~3%
• Gangkhar Puensum (7,570 m, Bhutan) — highest unclimbed (climbing banned >6,000 m)
