There is no mountain range in Antarctica called the "Epperly Mountains." It's likely you have a typo or are thinking of a different mountain range.

Antarctica does have many mountain ranges, including:

* Transantarctic Mountains: The largest mountain range in Antarctica, stretching for over 3,500 km (2,200 mi).

* Prince Charles Mountains: A range in East Antarctica, with peaks reaching over 3,000 meters (9,800 ft).

* Queen Maud Mountains: A range in East Antarctica, containing some of the highest peaks in Antarctica, including Mount Kirkpatrick (4,528 m or 14,856 ft).

* Sentinel Range: Part of the Ellsworth Mountains, with the highest peak in Antarctica, Mount Vinson (4,892 m or 16,050 ft).
