Felsite Island is a rock island long and high, lying at the head of Edisto Inlet within the northward stream of Edisto Glacier. It was named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, as descriptive of several prominent dikes of cream-colored igneous rocks (felsite) in its otherwise dark sedimentary rock formation.
