Main image

Mount Tyree is a major mountain in Antarctica, situated in the Sentinel Range of the Ellsworth Mountains and ranked as the continent’s second-highest peak. It is a steep, glaciated massif known for difficult conditions and remote access.

The mountain’s steep faces and extreme Antarctic weather make it a technical objective for well-equipped mountaineers. Climbs require long approaches over glaciers and coordination for Antarctic logistics.

Mount Tyree forms part of the central Sentinel Range near other high summits and contributes to the glaciated landscape of Western Antarctica. It is visited only by specialist expeditions due to its remoteness and environmental conditions.

The peak lies within Ellsworth Land, several hundred kilometres from the Antarctic Peninsula research bases; access typically involves aircraft to inland icefields followed by long ski or sled approaches.
