Also known as Pillar Point
Where: Clallam County, Washington (48.2° N, 124.1° W: paleocoordinates 47.9° N, 115.2° W)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Clallam Formation, Chattian (28.1 - 23.0 Ma)
• SPECIFIC STRATIGRAPHY: Monterey shale and sandstone. 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].
