Did George Mallory Climb Mount Everest First?

What It Covers

George Mallory's three Everest expeditions between 1921 and 1924 established the northern route to the summit, pushed human altitude records to 8,573 meters, and left an unresolved mystery about whether Mallory and Irvine reached the top before dying on June 8, 1924.

Key Questions Answered

• •Altitude progression: The 1922 expedition pushed human limits to 8,320 meters using supplemental oxygen — then controversial and considered unsporting — validating oxygen as essential. By 1924, Norton reached 8,573 meters without it, just 275 meters short of the summit, proving the peak was physically reachable.
• •Route discovery: Mallory's 1921 reconnaissance identified the Rongbuk Glacier to North Col line, establishing the only viable northern approach. This single route was used by British expeditions in 1922 and 1924, then replicated by a Chinese team in 1960, making it the definitive northern path to Everest's summit.
• •Evidence evaluation: When Mallory's body was recovered in 1999 at 8,155 meters, investigators found a fractured leg, head trauma, and a severed rope — indicating a fall while roped to Irvine. His Kodak camera, which could have confirmed a summit photo, was never found, leaving the central question unanswered.
• •Timing problem: O'Dell's 12:50 PM sighting of two figures near the Second Step creates a near-impossible schedule for a successful summit and return. Modern climbers aided by a fixed ladder still find the Second Step demanding, making a 1920s-era ascent in wool clothing within that timeframe highly questionable.
