A.3 <br />Grid <br />Max <br />Screen <br />Soil Description by Level <br />A.T.# <br />Date <br />Location <br />Depth <br />Size <br />(cultural materials are bolded) <br />bpgs <br />Construction-disturbed soil. <br />0-112cm: Dark grayish brown (I OYR 4/2) <br />crumbly/blocky clay loam, increased calcite <br />12 <br />8/4/15 <br />25NOE <br />112cm <br />1/4" <br />content, few sandstone clasts. Change in <br />consistency from previous auger tests, likely due <br />to disturbance from road-cut construction and <br />exposure of former colluvial talus deposits. <br />Construction-disturbed soil (which possibly <br />extend to a depth of l+m below the current road <br />surface). <br />0-70cm: grayish brown (I OYR 5/2 ) blocky clay <br />13 <br />8/4/15 <br />30NOE <br />70cm <br />1/4" <br />loam, increased calcite, modern fence tack and <br />wire fragment at 68cm. Light gray sandstone <br />clasts at base of test. Note: earthworms at 20- <br />40cm. <br />Construction-disturbed soil. <br />14 <br />8/4/15 <br />35NOE <br />27cm <br />1/4" <br />0-27cm: similar to above but mixed soils, <br />heavily disturbed due to road-cut construction. <br />15 <br />8/4/15 <br />ON5E <br />6cm <br />1/4" <br />0-6cm: brown (I OYR 4/3 ), silty clay, sandstone <br />bedrock contacted at 6cm. <br />16 <br />8/4/15 <br />5N5E <br />5cm <br />1/4" <br />0-5cm: brown (I OYR 4/3 ) silty clay, sandstone <br />bedrock contacted at 5cm. <br />17 <br />8/4/15 <br />ION5E <br />25cm <br />1/4" <br />0-25cm: dark brown (I OYR 3/3) silty clay. <br />Chert flake (FS 10) at 0-20cm. <br />0-14cm: dark grayish brown (I OYR 4/2) silty <br />18 <br />8/4/15 <br />15N5E <br />14cm <br />1/4" <br />clay with multiple small-medium sandstone <br />clasts (some oxidized red).
