is caused by an upthrust of plutonic rock damming the channel of 

 a little creek which now flows over falls and joins the Soleduck. 

 If utilized these falls will furnish 1000 to 5000 horse-power for the 

 running of mills, etc., depending upon the time of year. The po- 

 sition of the falls and the height of the lake ( there are no signs of 

 it ever having had a higher beach ) seem to indicate that the plu- 

 tonic dike which dams the stream is still being elevated. The lake 

 is alive with trout of excellent flavor. 



Pleasant lake is a little off of the road at the town of Tyee. It 

 is a very small lake. It contains many trout and is a good "duck 

 pond" in the fall of the year. It is due to the glacial damming of 

 a small side stream of the Soleduck, the stream now flowing over 

 the dam to the master stream. The lake once had an outlet farther 

 to tlie northeast, but this has been silted up in recent times. 



Lakes Sutherland and Crescent are in the east end of Clallam 

 county. As we have seen, they are in a partially abandoned chaa-, 

 nel of a stream that once flowed from the south by the way of 

 Wineton to join the Elwah. Indian creek is the remaining lower 

 part of that stream. The laking is due to the differential uplifting 

 of the bed of the stream in a former geological epoch accompanied 

 by a sinking of the bed in the laked places The glacial drift also 

 aided in this laking process. These lakes are seven and eighteen 

 miles respectively from Port Angeles, and the latter is five miles 

 from Port Crescent. Crescent lake is twenty square miles in area; 

 Lake Sutherland twelve. They are both beautiful expanses of 

 water surrounded by rucky walls, the walls surrounding Crescent 

 lake being from 2000 to 3000 feet higher than the lake. This lake 

 abounds in trout. It is now a suuimer resort, and cottages dot its 

 shores wherever there is room for a cottage to be erected.'^ These 

 lakes lie in the upper part of a synclinal trough, the northern end 

 of which is truncated by the waters of the strait in the vicinity of 

 Freshwater bay. 



Lakes Dickey and Ozette lie iu the western part of the Qaillayute 

 synclinal trough. Ttiey were protected frotn being filled by the 

 northern glaciers that swept the region by Clallam Peak, which di- 

 vided the glacier and caused it to pass around the present laked 



11. The Quileute Indians have a myth about the origin of Crescent lake, as follows: "Once, 

 in the valley which the lake now occupies, our people and the Clallams were having a big battle. 

 For two days the people killed each other. Then Mount Stormking became enraged. You know 

 the mountain that overlooks the north end of the lake from the east. Well, Mount Stormking 

 got angry (all things on earth were living beings then) and he took a great piece of rock from his 

 crest and hurled it down into the valley, killing all who were fighting and at the same time dam- 

 ming the stream with the great rock, so that it has been as it is now ever since, and no Indian 

 has gone near the place since that day." 



This myth causes the question to arise: Has there been volcanic activity in the region since 

 the Indian occupation? Undoubtedly it was a volcanic region in Eocene times, but as yet evi- 

 dence of later volcanic activity is wanting.
