Where: Clallam County, Washington (48.2° N, 122.1° W: paleocoordinates 47.9° N, 113.2° W)

• coordinate based on political unit

• outcrop-level geographic resolution

• GENERAL STRATIGRAPHY: The Clallam Formation is a predominantly marine sandstone with minor conglomerate and siltstone exposed along the Strait of Juan de Fuca in northwestern Washington. Marine molluscs occur throughout the 600 to 800 m thick formation but are especially abundant in the lowermost 240 m. Pillarian Stage age, a provincial time stratigraphic unit of late early Miocene age. Revised to Chattian following more recent work [Hendy, 7/2016].
