'''[[The Billboard]]''' is a massive granite monolith in the [[Sarnoff Mountains]] of the [[Ford Ranges]] of [[Westarctica]] standing just west of [[Mount Rea]] between [[Arthur Glacier]] and [[Boyd Glacier]]. It was discovered in November 1934 by a Second Byrd [[Antarctica|Antarctic]] Expedition (1933–35) sledge party under [[Paul A. Siple]], and is so named because of its form and appearance with vertical faces rising above the continental [[ice]].
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.


The summit was first visited by Bruce Luyendyk and Kuno Lecha by helicopter in January 1993 during expedition GANOVEX VII. In 1998-99, Christine Siddoway led a geological party from Colorado College that reached the summit by climbing a west route.
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.
