    A1—0 to 10 centimeters (0.0 to 3.9 inches); brown (7.5YR 4/4), dark brown (7.5YR 3/4), moist; cobbly loam; moderate fine granular, and weak fine subangular blocky structure; hard, friable, slightly sticky, slightly plastic; 21.0 very fine roots and 21.0 fine roots; 21.0 very fine interstitial and 21.0 fine interstitial pores; 10 percent by volume 76-?-250 millimeter unspecified fragments and 30 percent by volume 2-?-76 millimeter unspecified fragments; neutral, pH 6.6; clear wavy boundary. Lab sample # 82P02190
    A2—10 to 28 centimeters (3.9 to 11.0 inches); 7.5YR 4/5 (7.5YR 4/5), dark brown (7.5YR 3/4), moist; very gravelly loam; moderate medium subangular blocky, and moderate fine subangular blocky structure; hard, firm, moderately sticky, slightly plastic; 21.0 very fine roots and 21.0 fine roots; 21.0 very fine interstitial and 3.0 medium interstitial and 21.0 fine interstitial pores; 15 percent by volume 76-?-250 millimeter unspecified fragments and 45 percent by volume 2-?-76 millimeter unspecified fragments; moderately acid, pH 6.0; gradual wavy boundary. Lab sample # 82P02191
    Bt1—28 to 41 centimeters (11.0 to 16.1 inches); brown (7.5YR 5/4), dark brown (7.5YR 3/4), moist; extremely cobbly clay loam; weak fine subangular blocky structure; hard, firm, moderately sticky, moderately plastic; 3.0 very fine roots and 3.0 fine roots; 3.0 very fine interstitial pores; 30 percent thin clay films on surfaces along pores; 10 percent by volume 2-?-76 millimeter unspecified fragments and 40 percent by volume 76-?-250 millimeter unspecified fragments; slightly acid, pH 6.4; abrupt wavy boundary. Lab sample # 82P02192. This horizon appears to be discontinuous in some areas and in these cases the horizon above extends to the bedrock. On the case where the A2 goes to the bedrock, the Bt1 naturally is filling the fractures of the bedrock
    R—41 centimeters (16.1 inches); bedrock; fragments. Fractured basalt bedrock with few roots in fractures. A small amount of soil material occasionally present in fractures
