# Arctowski Peninsula

The Arctowski Peninsula (64°45′S 62°25′W﻿ / ﻿64.750°S 62.417°W﻿ / -64.750; -62.417﻿ (Arctowski Peninsula)) is a peninsula, 15 nautical miles (28 km; 17 mi) long in a north-south direction, lying between Andvord Bay and Wilhelmina Bay on the west coast of Graham Land, Antarctica.

## Location

The Arctowski Peninsula is on the Danco Coast on the west of the Antarctic Peninsula. It extends in a north-northwest direction from the Forbidden Plateau to the south into the Gerlache Strait to the north. Wilhelmina Bay is to the east. Across the Gerlache Strait the end of the peninsula faces the Solvay Mountains on Brabant Island to the north, and the Osterrieth Range on Anvers Island to the northwest. Rongé Island is west of the northwest side of the peninsula. The Laussedat Heights on the southwest side of the peninsula look over Andvord Bay to the west. The peninsula extends southeast to a line defined by Arago Glacier, which flows south into Henryk Cove, and Woodbury Glacier, which flows north into Piccard Cove.
Northern features include Cape Anna, Mount Fourcade, Orne Harbour, Spigot Peak, Selvick Cove, Zeiss Needle, Sable Pinnacles (Noire Rock) and Henryk Peak. Central features include Wild Spur, Henryk Glacier, Pulfrich Peak, Hubl Peak and Stolze Peak. Southern features include Porro Bluff, Orel Ice Fring, Laussedat Heights, Deville Glacier, Scheimpflug Nunatak, Fliess Glacier (flowing into Neko Harbour) and The Downfall.

## Geology

On the west coast of the Arctowski Peninsula, and the islands lying to the west, there are three main groups of exposed rocks. Permian(?) – Triassic metasediments of the Trinity Peninsula Group, Early Cretaceous lavas, agglomerates and tuffs of the Antarctic Peninsula Volcanic Group, and Mid-Cretaceous adamellite, granite, granodiorite, diorite, tonalite and gabbro plutons of the Andean Intrusive Suite. There are also basic and acid hypabyssal dykes that may date to the Late Cretaceous.

## Discovery and name

The Arctowski Peninsula was discovered by the Belgian Antarctic Expedition (BelgAE), 1897–99, under Adrien de Gerlache. The name, for Henryk Arctowski of that expedition, was suggested by the United States Advisory Committee on Antarctic Names (US-ACAN) for this previously unnamed feature.
