8. A section in Mr. E. Pullen's well on Quillayute prairie: 

 1. Clay and sand; sand at bottom of well; plenty of water 24 feet. 



4. A section ia Mr. Maxfield's well on Quillayute prairie: 



1. Loam 4 feet. 



2. Yellow clay 7 " 



3. Layers of loose gravel and of partly "cement " gravel 20 " 



This well has a little water in it; but it seeps away in the gravel. 

 The well has been abandoned. 



5. A section in Mr. Peterson's well on Forks prairie: 



1. Gravel, hard-pan, clay including boulders 75 feet. 



In this well, as in all the wells of Forks prairie, there is plenty 

 of water. It is obtained from the seepage from the Calawa river. 

 From the big bend in that river, its volume i.s much diminished. 

 Its water passes beneath Forks prairie as an undercurrent and has 

 its exit below the prairie in numerous springs, the water ultimately 

 reaching the Bogachiel river. This water seems to follow the old 

 channel of the Calawa prior to glacial times. 



6. A section at Forks prairie oti Mill creek, at the falls at Mr. 

 Iverson's sawmill: 



1. Loam 2 feet. 



2. Yellow clay 4 " 



3. A yellow cement cobblestone stratum, causing the falls in 



the stream 4 " 



4. Laminated, horizontal to the cross-bedded, massive, coarse 



to gravelly sand containing small cobbles— stratum totally 

 unlithified 10 feet +. 



7. A generalized section from Quillayute prairie to Dickey lake: 



1. Gravelly soil 2 feet. 



2. Yellow clay. This clay digs easily as a rule. At places, how- 



ever, it has a ' 'gumbo" nature, at others a jointed structure. 

 Where stumps had been burned it was noticed to be oxi- 

 dized, being bright red in color. It seems to be a good 

 brick and tile clay. The boulders in it attest its glacial 

 origin. Maximum thickness 20 " 



3. Blue clay, exposed under the yellow clay stratum along the 



streams. This clay when wet is sticky, and gives off a 

 bad odor. The water that seeps from it also has a bad 

 .taste. It is typical ground moraine material. In this 

 clay, as in the yellow clay above, there are lenses of 

 gravel. Strata of fire-clay were also seen in the bluffs 

 occasionally 40 feet +.
