In 1963, work in the area of Novopetrovka was continued by a section of the Far Eastern Expedition personnel of which included students of the Blago-veshchensk Pedogogical Institute under the direc-tion of AP Okladnikov. 1

Two to 2.5 km from the 1962 excavation, on a high picturesque promontory which slopes downward steeply to the Dunaika River valley, flakes and lamellar blades of a yellowish white to white gran-ular rocks-volcanic tuff-were again discovered. Among the surface finds, there are about two dozen small and large flakes obtained as a result of the preliminary working of core blanks, about a dozen
