The ''' | The '''U.S.A.S. Escarpment''' (76°0′S 130°0′W) is an expansive but discontinuous north-facing escarpment in [[Westarctica]]. | ||
It is about 320 kilometers (199 mi) long, extending roughly west to east along the 76th parallel south from where the elevation of the snow surface descends toward the [[Ruppert Coast]] and [[Hobbs Coast]]. The position of the escarpment coincides with the north slopes of the [[Flood Range]], the [[Ames Range]], and the [[McCuddin Mountains]]. | |||

The escarpment was observed by members of the United States [[Antarctica|Antarctic]] Service, 1939-41, and in ensuing scientific reports was referred to as the "76th Parallel Escarpment." | |||
The approved name is an acronym for the discovery expedition. | |||
