<br />Skylick Typical Sample "CC -2" Site and Soil Profile Description: Skylick loam in Map Unit
<br />66D was fully described and sampled at one representative site, CC -2, located in a portion
<br />of the SW1/4 of the NE1/4 of Section 34, T.6N., R.87W. The sample site is on a sloping
<br />ridge upper sideslope within the potential waste rock storage site outside of but adjacent to
<br />the current Seneca II Mine permit area. Sample site CC -2 has 12% slope; NE aspect; big
<br />sagebrush, mountain shrub species, and tall mixed grass and forb vegetation; slopewash
<br />alluvium over residuum at depth; stable surface with no erosion in the vicinity of the sample
<br />site location.

<br />channers, dark brown (10YR 3/3) moist; moderate coarse and medium granular structure;
<br />soft, friable, slightly sticky and slightly plastic consistence; common medium, fine, and very
<br />fine, and few coarse roots; noneffervescent; from lab data: pH =6.0 (moderately acid),
<br />EC =0.2 (nonsaline), SAR =0.3 (nonsodic), OM =5.6 %; gradual smooth boundary.
<br />A2 horizon — 5 to 16 inches; dark brown (10YR 4/3) sandy loam to loam with 2% small

<br />granular structure grading to moderate medium subangular blocky structure; slightly hard,
<br />friable, slightly sticky and slightly plastic consistence; common medium, fine, very fine, and
<br />few coarse roots; noneffervescent; from lab data: pH =6.1 (slightly acid), EC =0.1
<br />(nonsaline), SAR =0.5 (nonsodic), OM =1.5 %; gradual wavy boundary.
<br />• Bt1 horizon — 16 to 27 inches; yellowish brown (10YR 5/4) clay loam with 2% small gravel -

<br />subangular blocky structure; slightly hard to hard, friable to firm, sticky and plastic
<br />consistence; few medium, coarse, fine, and very fine roots; noneffervescent; from lab data:
<br />pH =5.9 (moderately acid), EC =0.1 (nonsaline), SAR =0.3 (nonsodic), OM =0.8 %; gradual
<br />wavy boundary.
<br />Bt2 horizon — 27 to 40 inches; light yellowish brown (10YR 6/4) clay loam, dark yellowish
<br />brown (10YR 4/4) moist; moderate medium subangular blocky structure; hard, firm, sticky
<br />and plastic consistence; noneffervescent; from lab data: pH =5.9 (moderately acid), EC =0.1
<br />(nonsaline), SAR =0.5 (nonsodic), OM =0.8 %; gradual wavy boundary.
<br />C1 horizon — 40 to 62 inches; light yellowish brown (10YR 6/4) clay loam, yellowish brown
<br />(10YR 5/4) moist; massive structure; hard, firm, sticky and plastic consistence;
<br />noneffervescent; from lab data: pH =6.3 (slightly acid), EC =0.1 (nonsaline), SAR =0.5
<br />(nonsodic), OM =0.5 %; gradual wavy boundary.
<br />C2 horizon — 62 to 76 inches; brownish yellow (10YR 6/6) sandy clay loam, dark yellowish
<br />brown (10YR 4/6) moist; massive structure; hard, friable, sticky and slightly plastic
<br />consistence; noneffervescent; from lab data: pH =6.4 (slightly acid), EC =0.1 ( nonsaline),
<br />SAR =1.1 (nonsodic), OM =0.4 %; gradual wavy boundary.
