blocked, but continuous from the Soleduck at Wineton through 

 Crescent and Southerland lakes and Indian creek to the Elwah. 

 The raising of the land of the peninsula on the side next the Strait 

 of Juan de Fuca dammed the stream, thus causing the lakes and 

 the wind gaps. Glaciation has also aided in this lake forming, as 

 we shall see later. The Elwah has quite a delta at its mouth. 



The Lyre river is the outlet of Lake Crescent. It has a great 

 fall throughout its entire course, except just where it enters the 

 Strait of Fuca. There it is forming a delta. Its course is along a 

 fault. It seems to be a very young stream, the lake having its out- 

 let formerly at its northeastern terminus by the way of Lake South- 

 erland to the Elwah river. 



Pysht river follows a fault a part of its course; the remainder of 

 its course is through a broad synclinal trough. It rises on the 

 divide between the Pacific and the Strait of Fuca near where the 

 Clallara-La Push road crosses that mountain ridge and flows into 

 Pysht bay of the Strait of Fuca. It has a very low lower course 

 running back from the coast several miles, it having filled a bay 

 here in recent times; and at the present time its silt is filling up 

 the bay at its mouth at a very rapid rate, so that the bay is now a 

 mud flat at low tide. In the early days the town of Pysht on this 

 bay WHS quite flourishing, but the filling of the bay became such a 

 hindrance to navigation that the place was abandoned and East 

 Clallam was made the depot for traflBc with the interior region, 

 though it has a much poorer natural road outlet into the interior 

 region. The Pysht river flat is a fine farming section. 



Clallam river rises in the highlands back of Clallam bay; flows 

 to the east and then to the north, entering the east side of Clallam 

 bay at East Clallam, following a fault line a considerable part of 

 its course. It carries considerable silt. It is diked in its lower 

 course so that it runs northward along the beach wall of the east 

 side of the bay nearly to Slip Point, a distance of about three-
