The Bearwallow series consists of well drained soils that are moderately deep to weathered bedrock. These soils formed in material weathered from sandstone. They are on hills and mountains. Slopes range from 5 to 75 percent. The mean annual precipitation is about 55 inches, and the mean annual air temperature is about 57 degrees F.

These soils are classified as fine-loamy, mixed, thermic Ultic Haploxeralfs.

Typical pedon of Bearwallow loam, in an area of Wolfey-Bearwallow complex, 30 to 50 percent slopes; 600 feet south and 600 feet east of the northwest corner of sec. 4, T. 13 N., R. 13 W., MDBM, Boonville Southeast quadrangle:

A—0 to 8 inches; pale brown (10YR 6/3) loam, dark brown (10YR 4/3) moist; massive; hard, friable, slightly sticky and slightly plastic; few very fine and fine roots; many very fine and common fine and medium tubular pores; moderately acid (pH 5.8); gradual wavy boundary.

Bt1—8 to 18 inches; pale brown (10YR 6/3) loam, dark brown (7.5YR 4/4) moist; weak fine and medium subangular blocky structure; slightly hard, very friable, slightly sticky and slightly plastic; few very fine and fine roots; common very fine interstitial and common very fine, fine, medium, and coarse tubular pores; few thin clay films lining pores; moderately acid (pH 5.8); gradual wavy boundary.

Bt2—18 to 26 inches; light yellowish brown (10YR 6/4) loam, variegated dark brown (7.5YR 4/4) and strong brown (7.5YR 5/6) moist; weak medium and coarse subangular blocky structure; hard, friable, slightly sticky and slightly plastic; few fine roots; few very fine interstitial and common very fine and fine and few medium and coarse tubular pores; common thin clay films lining pores; moderately acid (pH 5.6); gradual wavy boundary.

Bt3—26 to 34 inches; variegated light yellowish brown (10YR 6/4) and reddish yellow (7.5YR 6/6) loam, strong brown (7.5YR 5/6) moist; weak coarse subangular blocky structure; hard, firm, slightly sticky and slightly plastic; few fine roots; few very fine interstitial and common very fine and fine and few medium and coarse tubular pores; common moderately thick clay films on faces of peds; strongly acid (pH 5.4); clear wavy boundary.

Crt—34 to 40 inches; fractured, medium grained, soft sandstone that slakes in water; fractures are less than 1 millimeter wide and 3 to 10 centimeters apart; continuous moderately thick clay films on fracture faces.

The depth to soft bedrock ranges from 20 to 40 inches. The mean annual soil temperature ranges from 59 to 62 degrees F. The soil between the depths of 6 and 18 inches is moist in all parts from November 1 to May 1 and is dry in all parts from June 15 to October 1 in most years. The content of gravel ranges from 0 to 15 percent throughout.

The A horizon has color of 10YR 6/3, 6/4, or 7/4 or 7.5YR 6/4. Moist color is 10YR 3/2, 3/3, 4/3, or 4/4 or 7.5YR 3/2, 4/2, or 4/4. The content of clay ranges from 15 to 25 percent. Base saturation ranges from 75 to 90 percent. Reaction is moderately acid or slightly acid.

The Bt horizon has color of 10YR 6/3, 6/4, 6/6, or 7/3 or 7.5YR 6/6 or 7/6. Moist color is 10YR 3/3, 4/4, or 5/6; 7.5YR 4/2, 4/4, 4/6, or 5/6; or 5YR 5/6. The texture is loam or clay loam that contains 20 to 35 percent clay. Base saturation ranges from 60 to 75 percent. Reaction is strongly acid or moderately acid.
