This formation occupies "a great syncline between capes Elizabeth 

 and Granville, through the trough of which the Quinaielt river 

 empties into the sea. The formation in which this syncline is de- 

 veloped is therefore termed the Quinaielt. The Quinaielt consists 

 of over 2200 feet of conglomerates and shales, with minor quantities 

 of sandstone. The conglomerates are developed on the north of 

 the river, while the shale, with some underlying sandstone, occurs 

 south of it. Owing to the fact that faults limit the syncline on 

 both sides, it is impossible to determine positively which facies of 

 the formation, the conglomerate or the shale, was the older. How- 

 ever, it appears most likely that the latter represents the basal por- 

 tion of the formation. The beds contain well-preserved marine 

 fossils, and the conglomerates in particular considerable quantities 

 of almost unaltered wood and bark of trees, often in large frag- 

 ments." The fossils from this formation, listed below, make it 

 contemporaneous in age with the Purisima formation of central 

 California. 



Quillayute Formation. — This formation occupies the valley of 

 the Quillayute river and the country drained by its eastern tribu- 

 taries eastward at least to their respective middle courses, thence 

 westward to Waatch strait, the formation extending outward to the 

 coast now and then. The boundaries of the formation were not 

 ascertained. In the interior region, where exposed along the Bo- 

 gachiel river, it is composed of sandstone and bluish-gray shale; 

 the coast exposures are all conglomerates or a coarse gravelly 

 rock resting unconformably upon the older rocks exposed there. 

 The base of the formation was not seen in the interior region. 

 The thickness of the formation, consequently, was not ascertained 

 The sandstone series was found to be extremely fossiliferous, and 

 in it the fossils are beautifully preserved. Fossils were found at 

 two horizons — in the north bank of the Bogachiel river in a bluish- 

 gray rock in section 22, township 2 8 north, range 14 west of the 

 Willamette meridian, and in the bluff south of the abandoned chan- 

 nel of Maxfield creek on the south side of the Bogachiel river, in 

 sections 28 and 29 of the township and range above. But fossils 

 were obtained only from the latter location, as the former was be- 

 low the surface of the water of the river at the time visited. Be- 

 low is a description of the fossils obtained. 



Fossils of the Quillayute Formation (Lower? Pliocene) Exposed 

 in the Vicinity of Quillayute, Wash. 



The only Pliocene fossils so far mentioned in the state, so far as 

 the writer can learn, are those of the Quinaielt formation, some
