[4] The island has been identified as an Important Bird Area (IBA) by BirdLife International because it supports a breeding colony of about 3,000 pairs of gentoo penguins.

Other birds nesting at the site in smaller numbers include Adélie penguins, imperial shags, Wilson's storm petrels and south polar skuas.

Clayton Hill, a rocky mass 436 feet high, located in the northern portion of the Island, marks the highest elevation.

The ice cliffs at the head of the fiord frequently calve making the anchorage uncomfortable for vessels.

Vessels wintering in this site should moor by anchor cable to suitable points on the shore as well as taking anchorage underfoot.

Barriers of chain should be erected across the harbor entrance to prevent damage to the vessel by drifting ice.

[6] Huts built by the expedition are gone, although a cairn remains, along with a refuge hut built by Argentina in 1955, and a cross commemorating three members of the British Antarctic Survey who died in a 1982 attempt to cross the sea ice from Petermann to Faraday Station.

The original plaque has since been removed to the Museum National d’Histoire Naturelle in Paris, but the cairn, with a replica plaque, has been designated a Historic Site or Monument (HSM 27), following a proposal by Argentina, France and the United Kingdom to the Antarctic Treaty Consultative Meeting.

The refuge was inaugurated on February 6, 1955, and is operated by the Argentine Navy and was occupied periodically by personnel of the British Antarctic Survey of the former Faraday Station.
