Geology notes

All Clallam Formation assemblages represent inner sublittoral depths (less than about 100 m). Qualitative analysis of these assemblages indicates a gradual shallowing during deposition of the formation. The highest strata in the formation contain coal and are presumably non-marine.

Locality notes

Intertidal exposure of sandstone with scattered Vertipecten and Epitonium about 1.5 km east of Slip Point, Clallam quadrangle, Clallam County, Washington. Lat/long based on locality of Slip Point, Clallam county.
