Abstract
The Flattery Rocks, Quillayute Needles, and Copalis National Wildlife Refuges lie off the Pacific coast of the Olympic Peninsula between Cape Flattery and Grays Harbor. They have a total land area of 247 acres and consists of numerous small islands, sea stacks and rocks that rise above a wave-cut platform. The refuges are in a belt of intensely folded and faulted marine sedimentary and volcanic rocks of early Eocene to Pliocene age. Pleistocene glaciofluvial deposits blanket the Tertiary strata along this coastal belt. The disturbed belt borders the eastern margin of a depositional basin on the continental shelf that probably contains a thick sequence of late Tertiary rocks.
