Abstract
One of the most impressive outcrops of melange rocks along the Washington coast is exposed continuously for 2.5 mi (4km) in sea cliffs immediately south of the mouth of Raft River on the Quinault Indian Reservation, Grays Harbor County (Taholah 15-minute quadrangle) (Fig. 1). This site affords a rare opportunity for viewing a rock type that has resulted largely from tectonism and is particulary significant to an understanding of the general geology and tectonic framework of the Olympic Moun is 5 mi (8 km) north of Taholah and is reached by a gravel road. Because it is a beach locality on the Quinault Indian Reservation, permission to walk on the beaches must be obtained from the Quinault Tribal Office in Taholah. Instructions will alsobe given there for the best route from the road to the beach. Several trails are less than 0.25 mi (0,4 km) in length.Keywords
