_ ,~. . <br /> <br />t <br />EVANSTON SHALLOIJ VARIANT <br />The Evanston Shallow Variant consists of moderately deep well <br />drained soils formed in residuum and from alluvium and colluvium derived <br />from sandstone. They occur on rolling upland benches and sideslopes <br />and have slopes of 0 to 29 percent. <br />They are similar to and occur near Savage soils. They are also <br />similar to Grail Taxadjunct soils. Savage soils are deeper than 40 <br />inches and Grail Taxadjunct soils have mollic epipedons greater than <br />16 inches deep. Both have fine control section textures. Evanston <br />shallow Varian[ soils also occur near Castner and the Coberly Variant <br />soils. <br />. Evanston shallow 9ariant soils are classified as fine-loamy, mixed <br />Aridic Argiborolls. <br />This soil is a variant because it is shallower than the acceptable <br />range in depth for the Evanston Series. <br />Typical pedon of Evanston shallow Variant sandy clay loam, 12 <br />percent slope is located within 408,000:], 1,422,000E and 411,000N, <br />1,426,000E. <br />Al--0 to 2 inches; brown (lOYR S/3) sandy clay loam, dark brown <br />(lOYR 3/3) moist; weak fine granular structure; soft, friable, slightly <br />sticky and slightly plastic; common fine and few medium roots; many <br />fine interstitial pores; slightly effervescent; moderately alkaline; <br />clear smooth boundary. <br /> <br />2-205 <br />
