Artifacts recovered from archaeological excavations near the Willamette River in Lake Oswego, Oregon indicate the presence there of a Late Windust-Early Cascade Phase site possibly dating to 9,000 B.P. The assemblage includes 137 projectile points, bifaces or point fragments, nearly all of the Cascade-type. Two stem fragments and one complete point which are similar to those of the Windust Phase which dates 10,000-8,000 B.P. in the southern Columbia Plateau also were found. Stone knives, choppers, scrapers, hammerstones, cores and microblades also are included in the assemblage. No later type notched or stemmed points have been recovered from the site. If the hypothesized dates are valid, the site will be the oldest discovered to date in the Lower Willamette River-Portland Basin area. This thesis reports on the site, its excavation and its artifacts.
