Locality 35; basal conglomerate, point south of Fossil Rock, four miles 

 south of Empire, Coos Bay, Oregon. (H. Hannibal.) 



Locality 98; basal conglomerate, seacliffs at point three fourths of a mile 

 south of Five Mile Creek, Bandon, Oregon. (H. Hannibal.) 



Locality 77; sandstone, seacliffs from Cape Grenville northward for a 

 mile to long landslide, Taholah, Washington. (H. Hannibal.) 



Locality 79; shaly sandstone, seacliffs north of Quinaielt River bar, 

 Taholah, Washington. (H. Hannibal.) 



Locality So; sandstone, seacliffs from Cape Elizabeth northward for three 

 fourths of a mile to big landslide, Taholah, Washington] (H. Hannibal.) 



Two areas of soft semicoherent sandstone faulted into the Older 

 Tertiary and Mesozoic rocks on the coast of the Olympic Peninsula 

 near Taholah, Washington, contain a fauna evidently the same age. 

 The thickness here is perhaps 500 feet. 



The Elk River Formation (Upper Pliocene). 



Extending from the Goldwashers' cabin one and three fourths 

 miles southeast of Cape Blanco south to Garrison Lagoon near Port 

 Orford, Oregon, is a gently southward dipping clifif, essentially a 

 raised beach composed of sands and littoral gravels, blue and more 

 or less concretionized at the base but rusty and hardly consolidated 

 above, perhaps 250 feet thick near their contact with the Empire 

 sandstone lying to the north but gradually dropping down below sea 

 level to the south. This formation has been named by Diller^^ the 

 Elk River beds from an important stream which cuts through the 

 section. As a matter of fact Diller's name was given only to the 

 upper rusty portion of the section while the blue beds conformable 

 below were included with the Empire (Cape Blaco Beds) a pro- 

 cedure not borne out by the character of the fauna. It might be 

 added .that there is a marked discrepancy between the dip and strike 

 of the Empire beds and the overlying blue sands where the two 

 formations meet that was apparently overlooked by Diller. 



The fauna of the Elk River beds consists chiefly of recent species 

 but associated with them are others common to the Merced, thus 

 establishing the Pliocene age of the formation. In a general way 

 this fauna suggests the Deadman Island or Santa Barbara Pliocene 

 in the boreal facies of the fauna and the small percentage of extinct
