In this study we are working to test models for the geomorphic response to Eocene collision of the oceanic Siletz terrane with North America. This figure is a working tectonic reconstruction for the PNW region ~55 Myr ago, shortly before the start of terrane collision. Our field work is focused in southwest Oregon. The project is supported by a grant from the National Science Foundation (EAR-2417524).
