'''[[Mount Murphy]]''' is a massive, snow-covered and highly eroded shield volcano with steep, rocky slopes. It is directly south of the [[Bear Peninsula]] in [[Westarctica]]. The mountain is bounded by the [[Smith Glacier|Smith]], [[Pope Glacier|Pope]], and [[Haynes Glacier]]s. Its lower slopes terminate at the [[Crosson Ice Shelf]].
The '''[[Backer Islands]]''' are a chain of small islands at the south side of [[Cranton Bay]]. The islands trend northwest for 22 kilometers (12 nmi) from the [[ice shelf]] which forms the southern limit of the bay.


Mount Murphy was delineated from aerial photographs taken by [[U.S. Navy]] Operation Highjump in January 1947. Named by US-ACAN for Robert Cushman Murphy of the American Museum of Natural History, noted authority on [[Antarctica|Antarctic]] and sub-Antarctic bird life. While serving on a [[whaling]] ship, he charted the Bay of Isles region of South Georgia. During a 1968 biological survey of [[Marie Byrd Land]], Mount Murphy was one of the few locations where [[snow petrel]]s were discovered. In addition to the petrels, the survey team also found algae.
In 2011, scientists from the POLar Earth-observing NETwork (POLENET) traveled to the Backer Islands via a Twin Otter aircraft and installed a GPS monitoring site. This equipment is used to remotely monitor GPS and seismic data that will help scientists determine trends in ice sheet movement and other geophysical phenomena.

The Backer Islands are a chain of small islands at the south side of Cranton Bay. The islands trend northwest for 22 kilometers (12 nmi) from the ice shelf which forms the southern limit of the bay.

In 2011, scientists from the POLar Earth-observing NETwork (POLENET) traveled to the Backer Islands via a Twin Otter aircraft and installed a GPS monitoring site. This equipment is used to remotely monitor GPS and seismic data that will help scientists determine trends in ice sheet movement and other geophysical phenomena.
