<br />The "Woodlands" soil was fully described and sampled for laboratory analysis at two
<br />representative sites, S1 and S2. Sample locations are plotted on the soils map and are
<br />within the projected Gob Pile disturbance area.
<br />Woodlands Tvpical Soil Sample "S1" Site and Profile Description: 30% slope,
<br />southwest aspect; "JW" Juniper Woodland vegetation community; slopewash colluvium
<br />over residuum at depth; steeply sloping upland sideslope; stable surface, no erosion in
<br />vicinity of sample site location; moderate permeability.
<br />A horizon - 0 to 2 inches; brown (10YR 5/3) stony loam to clay loam with about 20%
<br />gravel, cobble, and stone-sized sandstone fragments, dark brown (10YR 4/3) moist;
<br />moderate medium granular structure; slightly hard, friable, slightly sticky and slightly
<br />plastic consistence; many medium, fine, very fine, and few coarse roots; slightly
<br />effervescent; from lab data: pH=7.3 (neutral), EC=0.4 (nonsaline), SAR=0.6 (nonsodic),
<br />OM=3.8%; gradual smooth boundary.
<br />Bw1 horizon - 2 to 8 inches; dark brown (10YR 4/3) stony loam to clay loam with about
<br />15% gravel, cobble, and stone-sized sandstone rock fragments, dark brown (10YR 3/3)
<br />moist; moderate medium subangular blocky structure; slightly hard to hard, friable, sticky
<br />and plastic consistence; many medium, fine, very fine, and few coarse roots; moderately
<br />effervescent; from lab data: pH=7.3 (neutral), EC=0.4 (nonsaline), SAR=0.6 (nonsodic),
<br />OM=3.8%; gradual wavy boundary.
<br />Bw2 horizon - 8 to 18 inches; brown (10YR 5/3) stony clay loam to sandy clay loam with
<br />about 15% gravel, cobble, and stone-sized sandstone rock fragments, dark brown (10YR
<br />4/3) moist; moderate medium subangular blocky to massive structure; hard, friable, sticky
<br />and plastic consistence; common medium, fine, very fine, and few coarse roots; strongly
<br />effervescent; from lab data: pH=7.4 (slightly alkaline), EC=0.3 (nonsaline), SAR=0.6
<br />(nonsodic), OM=4.3%; gradual wavy boundary.
<br />BCk horizon - 18 to 30 inches; pale brown (10YR 6.3) stony clay loam to sandy clay loam
<br />with about 20% gravel, cobble, and stone-sized sandstone rock fragments, brown (10YR
<br />5/3) moist; massive structure; hard, friable, sticky and plastic consistence; strongly
<br />effervescent; from lab data: pH=7.4 (slightly alkaline), EC=0.3 (nonsaline), SAR=0.8
<br />(nonsodic), OM=2.1 %; gradual wavy boundary.
<br />C horizon - 30+ inches; auger refusal (hit larger sandstone fragments); could not dig
<br />further, but do not believe it is sandstone bedrock yet; rock fragments >35%; not
<br />sampled.
<br />Woodlands Tvpical Soil Sample "S2" Site and Profile Description: 20% slope, south
<br />aspect; "JW" Juniper Woodland vegetation community; slopewash colluvium over
<br />residuum at depth; steeply sloping upland sideslope; stable surface, no erosion in vicinity
