Alamode Iceland (formerly Terra Firma Iceland ) is the largest island in the southeastern and Terra Firma Islands off the coast of the Antarctic Peninsula. It is in the Marguerite Bay off the west coast of Graham Lands.

To the west of the island is dumbbell Iceland, prior to the southwestern coast lies Pigmy skirt.

History

The island was by the British Graham Land Expedition ( BGLE ) under John Rymill in 1936 discovered and explored. First, given the name Terra Firma Iceland after a group of the expedition, should create depots camped here after the breakup of the sea ice. This name, however, was later given the entire archipelago.

It was given its present name by the Falklands Islands Dependencies Survey ( FIDS ) after a re-examination of the island in 1948 because of the similarity with a " Pie a la Mode", a fruit cake, which is often served with a scoop of ice cream on it.

Flora

Alamode Iceland is the southernmost place where the Antarctic hairgrass ( Deschampsia antarctica) and Antarctic the Perlwurz ( Colobanthus quitensis ), the only two seed plants of Antarctica occur.

Geology

The island has steep cliffs, which are surmounted by a dome of rock and snow, which rises to a height of 320 meters.

On the island there is a several thousand square meters large, relatively flat plain, the rock consists of dark gray felsic volcanic breccias. At this level, there are several pink granite boulders. During a time of stronger glaciation, the ice sheet extended to the mainland out to the Terra Firma Islands and beyond. Fragments of granite and other rocks were thereby removed from the mainland and underwater rock formations and dragged along by ice up to this level.
