The Bermel Escarpment is a snow and rock escarpment, 15 nautical miles long, extending from the base of the Ford Massif to King Peak, in the Thiel Mountains of Antarctica. The escarpment drops 300 to 400 metres from the Antarctic Plateau to the ice surface north of these mountains.

The Thiel Mountains are isolated, mainly snow-capped mountains of the Transantarctic Mountains System, located in the Ellsworth Land region of Antarctica. The mountain range is 45 nautical miles long, is located roughly between the Horlick Mountains and the Pensacola Mountains, and extends from Moulton Escarpment on the west to Nolan Pillar on the east. Major components include Ford Massif, Bermel Escarpment and a group of eastern peaks near Nolan Pillar.
