You may be thinking of the polar plateau, which is a flat expanse of ice. The polar plateau offers the longest earthly sight-light to the horizon -- the curvature of the earth -- which is about eight miles.
Ninety-eight percent of Antarctica is covered with an ice sheet, with its beaches and some nunataks exposed. Any plateau with be ice.

The polar plateau in Antarctica is a vast, flat region that covers a large part of the continent. It is located in the interior of Antarctica, around the South Pole, and is characterized by extremely cold temperatures and high elevations. The plateau is covered in thick ice sheets that can reach several kilometers in thickness.
The South Pole is located on the polar plateau of the continent of Antarctica.

The South Pole is an imaginary point on the Polar Plateau of Antarctica.
There may be. If you define a butte as a small, flat-topped hill -- smaller than a plateau or mesa -- these could exist under the 98% of the continent that is covered with an ice sheet. However, Antarctica is not known for its buttes.
The mountain range that spreads from Victoria Land to Rockefeller Plateau is the Transantarctic Mountains. It is one of the longest mountain ranges in the world, stretching for about 3,500 kilometers across Antarctica, separating East Antarctica from West Antarctica.
In Antarctica, some of the notable plateaus include the East Antarctic Plateau, which is the largest and coldest, and the West Antarctic Plateau. Other significant areas include the Antarctic Peninsula and the Shackleton Range. These plateaus are characterized by their high elevations, vast ice sheets, and extreme climatic conditions.
The Transantarctic Mountain Range stretches from Victoria Land on the Ross Sea to the Rockefeller Plateau in the interior of Antarctica. It divides East Antarctica from West Antarctica and is one of the longest mountain ranges in the world, with peaks exceeding 14,000 feet.
It could be the Antarctic Plateau, which covers most of the central part of Antarctica. This region where it is covered by this plateau doesn't have any mountains or other kind and is covered by about 3000 meters of ice.- which sometimes can be dangerous as it spreads out and goes towards the coastlines through the form of glaciers.. It is massive as the thickness of ice has been pressed below sea level. So in one way , if it were to be removed could lead to flooding of larger areas of Antarctica. On the other hand - if this icecap was to gradually melt, would lead to forming a land above sea level. The Antarctic Plateau is the second largest plateau after the Tibetan Plateau.
