Its area is 6,390 km2 (2,467 sq mi) and it is dominated by the dormant shield volcano Mount Siple, rising to 3,110 m (10,203 ft) — making this the 15th ranking island in the world by maximum elevation.

The feature was first indicated as an island on U.S. Geological Survey (USGS) maps compiled from ground surveys and U.S. Navy air photos, 1959–65.

Island and mountain were named by the United States Advisory Committee on Antarctic Names (US-ACAN) in 1967 in honour of the American Antarctic explorer Paul A. Siple (1909–1968), member of Admiral Byrd's expeditions.
