Abstract
The Bull River II site represents an important alpine tool production site in the central Alaska Range south of Broad Pass. Initial test excavations produced a sizable lithic assemblage and charcoal dated to the Younger Dryas. A lithic analysis comparing Bull River II and the undated Costello Creek assemblages reveals biface production was the primary activity at both locations. Discovered at relatively high elevations (>1000 m.a.s.l.), the sites reflect an underrepresented Eastern Beringian site type related to upland resource procurement and offer a basis for testing seasonal land-use models.
