Completion of the analysis of the artifacts from Chaluka, the old village site at Nikolski, Umnak Island, has brought to light a number of new observations on the Aleutian core and blade industry, orginally described in American Antiquity, Vol. 17, No. 1, pp. 52-54. The use of lamellar flakes is part of the earliest Aleut culture and most of the flakes, four fifths, are found below the three meter level. This earliest Aleut culture was introduced by the paleo-Aleut people.

These flakes were used mainly for scrapers and retouched on only one surface and along one or both edges. Quite a few of these are tanged, apparently for end-hafting. A number have well-worked points which, together with their general form, suggests their use as gravers. There are also two adze blades, two knives and at least one projectile point which appears to have been made from lamellar flakes.
