Vinson Massif: The Tallest Mountain in Antarctica

The highest peak in Antarctica is Vinson Massif, located in the Sentinel Range of the Ellsworth Mountains.

• Elevation: 4,892 meters (16,050 feet) above sea level.
• Coordinates: 78°35′S 85°25′W.
• Discovery: First sighted in 1958 by a U.S. Navy aircraft; first summited in 1966 by an American Alpine Club expedition led by Nicholas Clinch.

Vinson Massif is one of the "Seven Summits" (the highest mountains on each continent). Despite its extreme latitude, the climb is technically moderate (snow/ice slopes up to 40°), but the brutal cold, high winds, remoteness, and logistical complexity make it a serious mountaineering undertaking.
