Mount Everest vs. Mount Rainier: A 14,620-Foot Height Gap

The height difference between Earth's highest mountain and the Cascade Range's crown jewel is staggering—nearly three vertical miles.

Mount Everest (Sagarmatha / Chomolungma)

• Elevation: 8,848.86 m (29,031.7 ft) — 2020 China/Nepal joint survey.
• Location: Mahalangur Himal, Nepal/China border. 27.9881°N, 86.9250°E.
• Geology: Sedimentary/metamorphic (limestone, marble, schist) thrust over crystalline basement by India-Asia collision.

Mount Rainier (Tahoma / Tacoma)

• Elevation: 4,392 m (14,411 ft) — USGS 1999 survey.
• Location: Cascade Range, Pierce County, Washington, USA. 46.8523°N, 121.7603°W.
• Geology: Active stratovolcano (last eruption ~1,000 years ago); glacial cap (25 named glaciers, largest in contiguous US).

The Difference

4,456.86 m (14,620.7 ft) — Everest is 2.01× taller.

Contextualizing the Gap

• Everest's height above base (~3,650 m from South Col) is less than Rainier's total elevation.
• Rainier's prominence (4,392 m) > Everest's prominence (8,848 m) because Everest sits on the Tibetan Plateau (~4,500 m). Rainier rises from near sea level.
• Rainier has more glacial ice (3.5 km³) than any other contiguous US peak — comparable to many Himalayan peaks.
• Both are ultra-prominent peaks (prominence >1,500 m) — elite company.

Climbing Contrast

• Everest: 2-month expedition, supplemental O₂, $30–100K, 4–6% fatality rate (historical).
• Rainier: 2–3 day climb, no O₂, $2–5K guided, <1% fatality. 10,000+ attempts/year.

Same planet, same gravity—different leagues. Everest is the roof of the world; Rainier is the king of the Cascades. Both command absolute respect.
