ABSTRACT
The Pacific coast of North America is a hypothesized route by which the earliest inhabitants of the Americas moved southwards around the western margin of the Cordilleran Ice Sheet just after the last glacial maximum. To test this hypothesis, we have been using a stepwise process to aid in late Pleistocene archaeological site discovery along the coast. The steps involved include: (1) creating localized sea level curves; (2) generating detailed bare earth digital elevation models; (3) creating archaeological predictive models; (4) ground truthing these models using archaeological prospection; and (5) demonstrating that archaeological materials found date to the late Pleistocene. Here, we consider the use of these steps and how they have been employed to find late Pleistocene archaeological sites along the Pacific Coast of North America.

We are grateful to the Wilson Fund at the Center for the Study of the First Americans, Tula Foundation, and Hakai Institute for organizing and supporting the Stemmed Point Workshop and putting us all in the same room to talk about our research and compare results. Many archaeologists, First Nations members, students, and scientists have worked in the field and laboratory to help pull together the results we present here. We are grateful to them all.
