The '''[[Lindsey Islands]]''' (73°37′S 103°18′W) are a group of islands lying just off the northwest tip of the [[Canisteo Peninsula]] in the [[Amundsen Sea]]. The island group is the emergent part of a shelf that is less than 200 meters deep, and is formed of granitic rocks. The islands are relatively flat, the highest point being about 40 meters on the largest island. The islands are mostly ice free in summer, and two small freshwater ponds are present on the largest island.

He was responsible for geological research around many of [[Westarctica]]'s volcanic mountains. [[Mount LeMasurier]] was named in his honor.


Approximately 52 breeding pairs of [[Adélie penguin]]s were present on the Lindsey Islands as estimated from March 2011 satellite imagery. The colony occupies the eastern and southeastern coasts of the eastern island, and most of three main outliers and the northern half of the largest of the western group of islands. [[South polar skua]]s are also reported to breed on the islands, although numbers are not known.

Wesley E. LeMasurier is an igneous petrologist/volcanologist who specializes in the study of Cenozoic volcanoes in the Marie Byrd Land region of Antarctica. He was responsible for geological research around many of Westarctica's volcanic mountains. Mount LeMasurier was named in his honor.

Dr. LeMasurier's work includes studying the origin and evolution of Cenozoic volcanic rocks, the nature of the tectonic environment of volcanism, and the volcanic record of glacial history. In 1990, after conducting a survey of Mount Berlin, he declared the volcano to be "potentially active." Later, in 1994, during field work around Mount Siple, Dr. LeMasurier knocked off a piece of rock from the mountain and sent it to Ruth Siple, the widow of Paul A. Siple, for whom the mountain was named.
