Point Granville. In the north even the ridge (islands) along the 

 southern margin of the Quillayute-Ozettesyncline were submerged, 

 and the sea claimed as her own all the present land surface to the 

 very foot of the western extension of the Olympic axis. Marine 

 shells are found at Beaver post-office, twenty miles inland, as well 

 as in the stratified sands thirty-five feet above tide along the ocean 

 front near Point of Arches. After the subsidence there came from 

 the northward over the divide the great glacier, and, having scraped 

 off the top of the northern country, dumped its accumulated debris 

 in the pounding seas, extending its front outward beyond the pres- 

 ent shore-line and the now ofF-shore islands, probably even as far 

 out as the halibut banks, they likely being the final dumping- 

 ground. And by its advancing and retreating and the working 

 over of the material by the sea, the whole region, far beyond the 

 present shore-line, was filled up to a level with the top of the now off- 

 shore islands and to a height considerably above the former height of 

 the islands and former coast-line, as all are capped with from forty to 

 sixty feet of glacial material. Also, above the submerged area, the 

 now eastern tributaries of the Quillayute river had their inner val- 

 leys submerged or under tidal influence far inland from the then 

 shore-line and glacial-sheet. Consequently, they there sedimented 

 up their channels; Pleistocene deposits were found to underlie the 

 present bed of the Soleduck river, even as far as the Soleduek hot 

 springs, though for many miles below that it has now removed the 

 greater part of these deposits. 



That the glacier which glaciated this region as far south as the 

 Hoh river came from the north is attested by the fact that the up- 

 per country of the Quillayute valley shows no signs of having been 

 glaciated; also the granite boulders seen in the deposits near 

 Ozette lake and at many other places along the coast and in the in- 

 terior region are apparently rock from the Selkirks and Mount 

 Baker, far to the northward; there is no granite in the Olympics. 



On the whole, the formation west of the Hoh river is composed 

 mostly of sand and a poor grade of gravel, made up mostly of 

 ground-up sandstone from the neighboring hills, with a few granite 

 boulders scattered here and there. It reaches a thickness of 125 

 feet at Yellow Banks on the coast five miles east of the Ozette In- 

 dian village; but in the center of the Quillayute-Ozette it is likely 

 much thicker. At the surface it presents the characteristic features 

 of a glaciated region, subdued by the effects of a receding sea. 

 Near Mr. Albright's place, near Dickey lake, overwash sand and 

 gravel were found. McCalley lake, in section 20, having an area
