Descriptive name given in 1869 by Commander Meade, U.S. Navy (USN). It was called "Os(trov) Peschanyy," meaning "sandy (or gritty) island," by "Captain Lindenbert" in 1838. In 1868, it was called Indian Island by Commander Meade, U.S. Navy (USN), and Farewell Island, through a mistranslation of "Peschanyy," by G. D. Davidson, U.S. Coast and Geodetic Survey (USC&GS), in 1869. It has also been called Stony Island and Observatory Island (1883, Coast Pilot, p. 197). According to Aurel and Arthur Krause (1883, map), the Tlinget Indian name is Chlachatsch; according to W. H. Dall, U.S. Coast and Geodetic Survey (USC&GS), it is Shla-hatch (1883 Coast Pilot, p. 197).
