'''[[Mount Sidley]]''' is the highest dormant volcano in [[Antarctica]], a member of the Volcanic Seven Summits, with a summit elevation of 4,181–4,285 meters (13,717–14,058 ft). It is also the highest point in [[Westarctica]].
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 Sidley is a massive, mainly snow-covered shield volcano which is the highest and most imposing of the five volcanic mountains that comprise the [[Executive Committee Range]] of [[Marie Byrd Land]]. The feature is marked by a spectacular 5 km wide caldera on the southern side and stands north east of [[Mount Waesche]] in the southern part of the range.
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.
