Lyddan Island

Lyddan Island (coord|74|25|S|20|45|W|) is an ice-covered island at the southwest extremity of Riiser-Larsen Ice Shelf, separating it from Brunt Ice Shelf, about 20 miles off the Princess Martha Coast. The island is about 45 miles long and has three narrow arms in the form of a trefoil. It was discovered and plotted by W.R. MacDonald on November 5, 1967, in the course of a USN Squadron VXE-6 reconnaissance flight over the coast in LC-130 aircraft. Named by the Advisory Committee on Antarctic Names (US-ACAN) for Robert H. Lyddan, Chief Topographic Engineer of the United States Geological Survey (USGS), who has been active in the planning and supervision of Antarctic mapping operations since the 1950s.
