Was Mount Everest Called Peak XV? The Survey History Behind the Name

Yes — Mount Everest was originally designated "Peak XV" during the Great Trigonometrical Survey of India. The name "Mount Everest" came later.

Survey Designation

• 1847–1852: Survey teams under Andrew Waugh (Surveyor General of India) observed a high peak on the Nepal–Tibet border from stations in India (Darjeeling, etc.).
• Designation: Labeled Peak XV (15th major peak surveyed in the Himalayan series).
• Height Calculation: Radhanath Sikdar (chief computer) calculated 29,002 ft (8,839.8 m) in 1852 — confirmed as highest point on Earth.

Naming Controversy

• Local Names: Chomolungma (Tibetan: "Goddess Mother of the World"), Sagarmatha (Nepali: "Forehead of the Sky"). Waugh ignored them.
• Waugh's Proposal (1856): Name it after his predecessor, Sir George Everest (Surveyor General 1830–1843), who never saw the peak.
• Royal Geographical Society: Debated; officially adopted "Mount Everest" in 1865.
• Everest's Objection: George Everest opposed naming peaks after people; preferred native names.

Peak XV in Context

• Peak I–XIV were other Himalayan giants (e.g., Kanchenjunga = Peak IX, initially thought highest).
• Peak XV's calculated height surpassed all.
• Modern GPS: 8,848.86 m (2020 joint Nepal–China).

Why "Peak XV" Matters

• Reflects colonial science: mapping, claiming, naming without local consent.
• Illustrates the precision of 19th-century trigonometry (theodolites, baseline measurements, atmospheric refraction corrections).
• Sikdar's contribution long unrecognized; honored in India 2004 (postage stamp).

So: Peak XV was the survey identifier; Mount Everest is the imposed colonial name; Chomolungma/Sagarmatha are the indigenous names. All three coexist in history.
