'''''[[Caloplaca saxicola]]''''' is a small bright orange crustose [[lichen]] that grows on rock all over the world, including [[Antarctica]]. It is commonly called rock firedot lichen, jewel lichen or rock jewel lichen. It has short, inflated looking elongate 1–2 mm and .3-.1 mm wide lobes that have an abrupt margin at the edge, and no prothallus.
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.


''C. saxicola'' is one of the few [[lichen]]s found in [[Westarctica]], and is likely the most southerly plant life. The [[Caloplaca Hills]] were named for this lichen, which grows on the rocks there. This lichen occurs over a portion of northern North America as far north as the Canadian Boreal forests, where Black Spruce is a dominant tree. In California, it is one of the most common saxicolous lichens.
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.
