<br />DESCRIPTION AND CLASSIFICATION
<br />plasticity, decreased sand content
<br />22.5-24.5: SANDY CLAY - Mostly medium plastic fines, with at
<br />15% very fine grained sand, subangular grains, stiff to very stiff,
<br />moist, tan (CL) (GLACIAL DEPOSITS]
<br />24.5-26.2: SANDSTONE - mostly sand, fine to medium grained,
<br />subangular to subrounded,10% non-plastic fines, slightly to -
<br />moderately cemented, moderately friable, nearly horizontal
<br />bedding, slightly to moderately weathered, slightly fractured, soft to
<br />moderately soft, slightly moist, light tan.
<br />26.2-27.0: CLAYSTONE - Mostly clay, medium plasticity, nearly
<br />horizontal bedding, moderately weathered, moderately fractured,
<br />moderately soft, slightly moist
<br />27.0-29.5: SANDSTONE - similiar to 24.5-26.2
<br />29.3-29.5: Bottom 0.2ft highly weathered.
<br />29.5-31.5: SILTY CLAYSTONE - Mostly medium plastic fines,
<br />nearly horizontal bedding, moderately weathered, slightly to
<br />moderately fractured, moderately soft, moist, blue, red, tan, gray,
<br />brown.
<br />31.5-32.7: SANDSTONE - Mostly sand, fine grained, subangular,
<br />10% non-plastic fines, slightly to moderately cemented, nearly
<br />horizontal bedding, slightly to moderately weathered, slightly to
<br />moderately fractured, moderately soft, slightly moist, blue.
<br />32.7-34.5: CLAYSTONE - Mostly medium plastic fines, nearly
<br />horizontal bedding, moderately weathered, moderately to highly
<br />fractured,soft to moderately soft, slightly moist, blue.
