EXPLANATION:
Stratigraphic Unit 0 GEOLOGIC CONTACTS SOIL DESCRIPTIONS Stratigraphic Unit A Ctayey Sand (SC), Silty Sand (SM), Sand and Gravelly Sand (SP-GP), Sifts and Clays (ML and CL);
brown to red. coarse grained horizons dense poorly sorted; angular to subangular very fine to coarse quartz end lithic fragments; cobbles to 10" diameter, fines approximately 12-35%. Fine grained horizons:
low to medium plasticity, stiff to hard, thinly interbedded.
Horizons discontinuous horizontally and verti-cally Locally crossbedded SOLID located withm I inch LONG DASH; located withinld inches re Silty and Sandy Clay (CL), Clayey and Sandy Sgt (ML), Gravelly Sand (SP), Clayey Sand (SC): brown; cease grained horizons are dense, poorly sortedfroorly graded, angular to subangular, very fine to coarw quartz and lithic fragments, gravel to 2" diameter, fines 12%i to 35%. Fine grained horizons low to medium plasticity, stiff to hard. Horizons are discontinuous both horizontally and vertically, nterme-diate contacts gradational. Caliche nodules and root casts are abundant.
Silty Clay (CL), Clayey Silt (ML); brown, low to medium plasticity, dry to moist, stiff to very stiff.
