Normal Route of Mount Vinson (Branscomb Glacier Route)
The Normal Route on Mount Vinson ascends the gentle yet crevasse-riven Branscomb Glacier to gain the high saddle between Mount Shinn and Mount Vinson, continuing across the Vinson Plateau to the corniced rocky summit horn. First climbed in December 1966 by the American Antarctic Mountaineering Expedition led by Nicholas Clinch, it is the standard route for Seven Summits mountaineers.

Tactical & Camp Notes
The sun circles the horizon without setting, but when storms strike, temperatures drop drastically within minutes and visibility becomes zero in blinding spindrift.
Identified Objective Hazards
- •Extreme polar cold with windchill values regularly plunging below -50°C causing rapid frostbite
- •Fierce katabatic windstorms exceeding 120 km/h capable of shredding high-altitude expedition tents
- •Hidden polar crevasses across the Branscomb Glacier requiring perpetual rope team vigilance
- •Hypoxia exacerbated by the thinner atmosphere at polar latitudes due to barometric depression
Historical Context
First climbed on December 18, 1966, by Nicholas Clinch, Barry Corbet, John Evans, and Peter Anderson during the joint American Alpine Club / National Geographic expedition.

Mountain Ascended
Mount Vinson / Vinson Massif
Mount Vinson is the highest peak in Antarctica at 4,892 metres (16,050 ft), situated in the Sentinel Range of the Ellsworth Mountains approximately 1,200 kilometres from the South Pole. As the summit of Antarctica, it forms one of the celebrated Seven Summits. First sighted by a US Navy aircraft in January 1958 and named after Georgia congressman Carl Vinson, the peak was conquered on December 18, 1966, by a team led by Nicholas Clinch and Barry Corbet during the historic American Antarctic Mountaineering Expedition. While technically moderate via the Branscomb Glacier, climbing Mount Vinson demands extreme endurance against temperatures plunging to -40°C and ferocious katabatic blizzards.

1966 Nicholas Clinch American Antarctic Expedition Historic First Ascent of Mount Vinson
On December 18, 1966, an elite four-man summit party—Nicholas Clinch, Barry Corbet, John Evans, and Peter Anderson—achieved the maiden first ascent of Mount Vinson (4,892 m), the highest point in Antarctica. Supported by the American Alpine Club, National Geographic, and the US Navy, the expedition placed all ten team members atop Vinson over consecutive days before conquering Mount Tyree and Mount Shinn in complete polar safety.

1985 Dick Bass Mount Vinson Ascent: Completion of the Original Seven Summits
On April 30, 1985, 55-year-old American businessman Dick Bass reached the summit of Mount Vinson (4,892 m) in Antarctica, accompanied by David Breashears and Giles Kershaw. The ascent finalized Bass's visionary quest to become the first human in history to conquer the highest mountain on each of the seven continents, establishing the Seven Summits as a global benchmark of endurance.

1986 Reinhold Messner Mount Vinson Ascent: The Messner Seven Summits
On December 3, 1986, legendary alpine purist Reinhold Messner reached the summit of Mount Vinson (4,892 m) in Antarctica. Coming just weeks after completing his historic conquest of all fourteen 8,000-metre peaks, Messner's ascent of Vinson finalized the 'Messner List' of the Seven Summits, advocating for Australasia's technical Carstensz Pyramid over Australia's walk-up Mount Kosciuszko.
