Sentinel Range
The Sentinel Range forms the majestic northern portion of the Ellsworth Mountains in West Antarctica. Overlooking the Ronne Ice Shelf, this glaciated polar range contains Antarctica's highest summits, including Mount Vinson (4,892 m) and the vertical rock ramparts of Mount Tyree (4,852 m). Discovered by Lincoln Ellsworth in 1935, the range is known for severe polar cold, katabatic storms, and pristine sub-zero glacier basins.

Documented Peaks in Sentinel Range
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.
Mount Tyree
Mount Tyree is the second-highest mountain in Antarctica at 4,852 metres (15,919 ft), located just 13 kilometres northwest of Mount Vinson in the Sentinel Range. In stark contrast to the rounded, glaciated ramps of Mount Vinson, Mount Tyree is a terrifying, sheer horn of dark metamorphic rock and steep blue ice, rising over 2,000 metres directly from its surrounding glaciers. First ascended on January 6, 1967, by Barry Corbet and John Evans via the Northwest Face, it is widely acknowledged as the most technically demanding and formidable high peak in all of Antarctica, having seen fewer than twenty ascents in mountaineering history.
