Mount Tuck is a tall, pyramid-shaped mountain in Antarctica. It stands 3,560 meters (about 11,680 feet) high. This impressive peak is located at the start of the Hansen Glacier. It is also the highest point of the Doyran Heights. These heights are part of the Sentinel Range, which is found within the larger Ellsworth Mountains.

Mount Tuck rises above several glaciers. To its north is the Hansen Glacier. To its south, you'll find the Hough Glacier. The upper Dater Glacier is to its west. A pass called Manole Pass separates Mount Tuck from Veregava Ridge to the northwest.

How Mount Tuck Was Discovered and Named

Explorers first mapped Mount Tuck between 1957 and 1959. This mapping was done by the United States Geological Survey (USGS). They used surveys and aerial photos taken by the United States Navy.

The mountain was later given its name by the Advisory Committee on Antarctic Names (US-ACAN). This committee is responsible for naming places in Antarctica. They named it after Lieutenant John Tuck Jr.. He was a leader who supported the U.S. Navy operations at the South Pole Station in 1957.
