Ardery Island (Ardery Island)
Ardery Island is a steep, rocky island, about 1 km long, lying 1.8 km west of Odbert Island in the Windmill Islands of Antarctica.
The island was first mapped from air photos taken by the US Navy's Operation Highjump and Operation Windmill in 1947 and 1948. It was named by the US Advisory Committee on Antarctic Names (US-ACAN) for Major E. R. Ardery, an Army Corps of Engineers observer who assisted Windmill parties in establishing astronomical control stations between Wilhelm II Coast and Budd Coast during the 1947–48 season.
Cave Ravine is a ravine in the western part of the island. It was first mapped by Operation Highjump and later visited in 1961 by M. N. Orton, a medical officer at Wilkes Station. It was so named by the Antarctic Names Committee of Australia (ANCA) for a cave in the western wall of the ravine. Cave Landing is an ice foot near Cave Ravine which affords a boat landing in spring and summer. It was discovered by Orton during his visit to Cave Ravine, and named by ANCA. Orton Cave is a cave in the western wall of Cave Ravine, also discovered by Orton, for whom it was named by ANCA.
Mast Point is the westernmost point of the island. It was named by US-ACAN for Clarence W. Mast, a member of the Wilkes Station party of 1958.
Hiegel Passage is the sea passage between Ardery Island and Holl and Ford Islands to the south. It was named by the US-ACAN for Commander James A. Hiegel, leader of Mobile Construction Battalion Number One, who supervised the construction of Wilkes Station in February 1957.

Country - Antarctica
Antarctica is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of 14200000 km2. Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of 1.9 km.
Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over 200 mm along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost 60 m. Antarctica holds the record for the lowest measured temperature on Earth, −89.2 C. The coastal regions can reach temperatures over 10 C in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation occurs, it is mostly in the form of lichen or moss.
