<br />ENGINEERING AND GEOLOGICAL
<br />DESCRIPTION AND CLASSIFICATION
<br />.0-4.5: CLAY - Mostly medium to high plastic tines, about
<br />ne grained sand, subangular to subrounded grains and about
<br />0-15% ravel, subangular to subrounded grains, very stiff, moist,
<br />ad (CL) [GLACIAL DEPOSITS]
<br />i.5-9.5: CLAY- Mostly medium plastic fines, about 30% fine
<br />(rained sand, subangular grains, about 10% fine gravel,
<br />;ubangular to subrounded grains, stiff, moist, radish brown with
<br />;olored inclusions (CL) [GLACIAL DEPOSITS]
<br />3.75-9.5: Increased sand content to about 75%, fine to medium
<br />]rained, subangular
<br />3.5-13.3: SANDY CLAY - mostly medium plastic fines, about 35%
<br />Ine to medium grained sand, subangular, stiff, moist, red. (CL) -
<br />GLACIAL DEPOSITS]
<br />13.3-14.5: SILTY SAND - mostly fine to medium grained sand,
<br />subangular grains, less than 15% fines, medium plastic, medium
<br />dense, moist, red (SM) [GLACIAL DEPOSITS].
<br />14.5-17.0: SILTY CLAY - Mostly medium plastic fines, with about
<br />15% very fine grained sand, subangular grains, stiff, moist, redish
<br />brown, (CL) [GLACIAL DEPOSITS].
<br />14.7: Color change from redish brown to green to tan.
<br />16.0: sandstone cobble, composition similiar to 24.5-26.2
<br />17.0-19.5:SILTY CLAY - Mostly low to medium plastic fines, with
<br />about 30% fine to medium grained sand, subangular grains, stiff,
<br />moist, (CL) [GLACIAL DEPOSITS]
<br />17.0-17.3: Medium stiff
<br />18.75-19.5: Increased sand content to about 70%.
<br />19.5-20.0: CLAY - Possible sluff from pushing Sharon Tube at
<br />19.5', mostly fines, medium plasticity, soft, very moist, red, possil
<br />failure material.
<br />20-22.5: INTERBEDED CLAYS AND SANDS - Clay is mostly
<br />medium plastic fines. stiff, moist. Sand is mostly widely graded
<br />fine to coarse grained sand, subangular grains, medium dense,
<br />moist, red, brown, green gray (CL to SC) [GLACIAL DEPOSITS]
<br />21 R With r,Ior chance from red to oreen, grey, increased I
