Sack Island (Sack Island)
Sack Island is a rocky island, 0.4 nmi long, lying 0.2 nmi east of the south end of Holl Island, in the Windmill Islands. First mapped from aerial photographs taken by U.S. Navy Operation Highjump in February 1947. Named by the Advisory Committee on Antarctic Names (US-ACAN) for Norman F. Sack who served as photographer's mate with the central task force of U.S. Navy Operation Highjump, 1946–47, and assisted Operation Windmill parties in obtaining photographic coverage of this area in January 1948.

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.
