    Oi—0 to 10 centimeters (0.0 to 3.9 inches); partially decomposed organic matter; fragments. Lab sample # 79P02178. Organic layer consisting of slightly decomposed alpine vegetation.
    A1—10 to 18 centimeters (3.9 to 7.1 inches); dark brown (7.5YR 3/2) interior, dark grayish brown (10YR 4/2) interior, dry; silt loam; weak fine subangular blocky structure; soft, friable, nonsticky, nonplastic; moderately smeary; 2.5 fine and medium roots; fragments; strongly acid, pH 5.4, hellige-truog; abrupt irregular boundary. Lab sample # 79P02179. common fine and medium roots
    B—18 to 40 centimeters (7.1 to 15.7 inches); dark reddish brown (5YR 3/3) interior, reddish brown (5YR 4/3) interior, dry; silt loam; weak coarse subangular blocky structure; soft, friable, nonsticky, nonplastic; moderately smeary; 0.5 fine roots; fragments; moderately acid, pH 5.8, hellige-truog; clear smooth boundary. Lab sample # 79P02180. Thie B horizon is extremely churned due to frost action which makes it difficult to describe individual subhorizons within the B. Because of this the 8 to 30 cm depth has been broken into the two predominant soil materials based on color.; few fine roots
    B—40 to 40 centimeters (15.7 to 15.7 inches); yellowish brown (10YR 5/6) interior, very pale brown (10YR 7/3) interior, dry; silt loam; weak coarse subangular blocky structure; soft, friable, nonsticky, nonplastic; moderately smeary; 0.5 fine roots; fragments; moderately acid, pH 6.0, hellige-truog; clear smooth boundary. Lab sample # 79P02181. few fine roots
    2Ab—40 to 48 centimeters (15.7 to 18.9 inches); brown (10YR 5/3) interior, dark brown (7.5YR 3/2) interior, dry; loam; weak medium subangular blocky structure; soft, friable, nonsticky, nonplastic; fragments; moderately acid, pH 5.8, hellige-truog; gradual smooth boundary. Lab sample # 79P02182
    2C—48 to 162 centimeters (18.9 to 63.8 inches); partially decomposed organic matter; fragments. Lab sample # 79P02183. Extremely decomposed granitic rock with pockets of completely disintegrated bedrock of loamy texture.
