The possibility of a culture preceding that of the earliest paleo-Aleuts in the Aleutian Islands has been recognized for a long time. However, the researches of Jochelson and Hrdlicka provided no substantiation for such a possibility. Subsequent excavations carried out by the Peabody Museum of Harvard University in 1948, a party sponsored by the Arctic Institute of North America in 1949, and a party from the University of Oregon in 1950 have similarly failed to reveal any culture earlier than that of the paleo-Aleuts. Re-examination of an existing collection suggests the presence of such a culture in the Aleutian Islands
