Description (see definition): A major subglacial trench of West Antarctica which lies S of Byrd Subglacial Basin and is separated from it by a ridge except for a juncture of the two features near their E termination. From that juncture near Ellsworth Mountains, the trench extends WSW along the N side of Ellsworth Subglacial Highlands to c. 81S, 120W. A maximum depth of -2,540 m is reported in the W part of the trench. Named by Advisory Committee on Antarctic Names (US-ACAN) in 1961 for Charles R. Bentley, chief traverse seismologist at Byrd Station, 1957-59; leader of the 1957-58 seismic traverse that determined the existence of this trench and recorded its depth. This amended description follows further subglacial delineation by the SPRI-NSF-TUD airborne radio echo sounding program, 1967-79.
