The Bach Ice Shelf (72°S72°W) is an ice shelf which is irregular in shape and 45 miles (72 km) in extent, occupying an embayment in the south part of Alexander Island entered between Berlioz Point and Rossini Point. The ice shelf supports the south face of the Beethoven Peninsula, along with some minor extensive peninsulas and small inlets (Weber Inlet, Boccherini Inlet etc.) Bach ice shelf also supports the north side of the Monteverdi Peninsula. A minor embayment in this position first appeared on the charts of the US Antarctic Service, which explored the south part of Alexander Island by air and from the ground in 1940. The ice shelf was delineated by Derek J.H.
