The research in this volume derives from investigations conducted in connection with proposed widening and realignment of the Paulina-East Lake Highway, located within the caldera of Newberry Volcano. Formal evaluation of 13 localities and data recovers at four sites produced a wealth of information regarding human uses of the caldera and vicinity throughout the Holocene.
Initial evaluations were conducted in 1990 at nine sites. Text excavations the following year were conducted at four additional localities. The results of data recovery excavations undertaken at four sites in 1992 are reported in this volume.
