- Geology: Sedimentary/metamorphic rock (limestone, marble) thrust up by Indian-Eurasian plate collision (~50 Ma). Still rising ~4 mm/yr.
Other "Highest" Claims
- Mauna Kea (Hawaii): Tallest from base (ocean floor) = 10,210 m. Summit 4,207 m above sea level.
- Chimborazo (Ecuador): Farthest from Earth's center (equatorial bulge) = 6,384.4 km from center. Summit 6,263 m above sea level.
- K2 (Karakoram): 2nd highest above sea level (8,611 m) — harder, deadlier.
Climbing Today
~800 summits/year (pre-COVID). Commercial expeditions ($30k–$100k+). Permits: Nepal $11k, China $10k+. Crowding, waste, climate change (glacial melt) are critical issues. Death rate ~1–2% (historical).
