    AP—0 to 15 centimeters (0.0 to 5.9 inches); very dark grayish brown (10YR 3/2) gravelly clay loam; weak fine angular blocky structure; friable, moderately sticky, moderately plastic; 21.0 roots; fragments; moderately acid, pH 5.8, unspecified; abrupt smooth boundary. Lab sample # 40A04093. Many fine volcanic fragments.
    B—15 to 38 centimeters (5.9 to 15.0 inches); dark brown (10YR 3/3) gravelly clay loam; moderate fine angular blocky structure; friable, slightly sticky, moderately plastic; 21.0 roots; clay films; fragments; neutral, pH 7.0, unspecified; clear smooth boundary. Lab sample # 40A04094. Many volcanic fragments of various shapes and sizes. These fragments appear to be a stone line at the lower depth of this horizon.; patchy - phpvsfiid 187152; patchy - phpvsfiid 187152
    2C1—38 to 56 centimeters (15.0 to 22.0 inches); brown (10YR 4/3) gravelly sandy clay loam; moderate coarse angular blocky parts to prismatic structure; 21.0 roots; 21.0 fine pores; fragments; neutral, pH 7.0, unspecified; clear smooth boundary. Lab sample # 40A04095. Many fine volcanic fragments; there appears to be a stone line at the bottom of this layer.
    2C2—56 to 74 centimeters (22.0 to 29.1 inches); brown (10YR 4/3) gravelly sandy clay loam; massive; 21.0 fine pores; fragments; slightly alkaline, pH 7.6, unspecified; clear smooth boundary. Lab sample # 40A04096. Many fine volcanic fragments; there appears to be a stone line at the bottom of this layer; there appears to have been a thin organic layer in this horizon.
    3C3—74 to 102 centimeters (29.1 to 40.2 inches); sandy clay loam; fragments. Lab sample # 40A04097. This layer is 90 percent volcanic fragments in all shapes and sizes.
    4C4—102 to 127 centimeters (40.2 to 50.0 inches); dark reddish brown (5YR 3/3) clay loam; massive; slightly hard; fragments; clear smooth boundary. Lab sample # 40A04098. Fragments of old soft charcoal were found in this and the next horizon - carbon dates would be of interest.
    4C5—127 to 147 centimeters (50.0 to 57.9 inches); dark reddish brown (5YR 3/4) clay loam; massive; slightly hard; 21.0 fine pores; fragments. Lab sample # 40A04099
