TAXONOMIC CLASS: Fine, mixed, active, mesic Typic Argiudolls
TYPICAL PEDON: Blueye gravelly silt loam - on a 9 percent slope in woodland at an elevation of 1,145 feet. (Colors are moist soil unless otherwise stated.)
Ap--0 to 9 inches; very dark grayish brown (10YR 3/2) gravelly silt loam, grayish brown (10YR 5/2) dry; weak fine granular structure; very friable; many very fine roots; 15 percent chert gravel and 5 percent sandy dolomite gravel; slightly alkaline; clear smooth boundary.
A--9 to 14 inches; very dark grayish brown (10YR 3/2) gravelly silt loam, grayish brown (10YR 5/2) dry; weak very fine subangular blocky structure parting to weak very fine granular; friable; many very fine roots; 15 percent chert gravel and 5 percent sandy dolomite gravel; slightly alkaline; clear smooth boundary. (Combined thickness of the A horizon is 10 to 18 inches.)
2Bt1--14 to 21 inches; strong brown (7.5YR 4/6) gravelly clay; moderate fine angular blocky structure; firm; common very fine roots; few faint clay films on faces of peds; 20 percent chert gravel and 10 percent sandy dolomite gravel; moderately alkaline; gradual smooth boundary.
2Bt2--21 to 30 inches; red (2.5YR 4/6) and brown (7.5YR 5/4) gravelly clay; strong medium prismatic structure parting to moderate medium angular blocky; very firm; common very fine roots; few faint clay films on faces of peds; 20 percent chert gravel and 10 percent sandy dolomite gravel; moderately alkaline; gradual smooth boundary.
2Bt3--30 to 39 inches; yellowish brown (10YR 5/4) and red (2.5YR 4/6) gravelly clay; strong medium prismatic structure parting to moderate medium angular blocky; very firm; common fine roots; few faint clay films on faces of peds; 15 percent chert gravel and 15 percent sandy dolomite gravel; moderately alkaline; abrupt wavy boundary. (Combined thickness of the Bt horizon is 8 to 30 inches.)
2R--39 inches; dolomitic limestone.
TYPE LOCATION: Barry County, Missouri; about one mile north of Eagle Rock; 750 feet south and 30 feet east of the northwest corner, sec. 4, T. 21 N., R. 26 W.; USGS Eagle Rock topographic quadrangle; lat. 36 degrees 33 minutes 54 seconds N. and long. 93 degrees 45 minutes 41 seconds W.
RANGE IN CHARACTERISTICS:
Depth to Bedrock: 20 to 40 inches
A or Ap horizon
Hue: 7.5YR or 10YR
Value: 2 or 3
Chroma: 1 to 3
Fine-earth: silt loam, loam, clay loam, or silty clay loam
Total Rock fragments: 15 to 50 percent gravel

Note: Some pedons have a BA or AB horizon with properties similar to the A horizon.
2Bt horizon
Hue: 2.5YR to 10YR

COMPETING SERIES: This is the Romona series. Romona soils have 30 to 75 percent rock fragments in the lower part of the series control section.
GEOGRAPHIC SETTING: Blueye soils are on ridgetops and side slopes of hills. Slopes range from 3 to 50 percent. They formed in cherty hillslope sediments and the underlying clayey residuum from cherty dolomite. Mean annual temperature ranges from 54 to 57 degrees F, and the mean annual precipitation ranges from 38 to 44 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the similar Bardley and Gatewood soils and the Hailey, Mano, Moko, Nixa and Ocie series. Hailey, Mano, Nixa and Ocie soils do not have a mollic epipedon. In addition, Hailey soils have more than 35 percent rock fragments and less than 35 percent clay in the control section. Mano soils are very deep and Ocie soils are deep. Moko soils are very shallow and shallow. Nixa soils have a fragipan. These soils are on similar positions or downslope.
DRAINAGE AND PERMEABILITY: Well drained. Runoff is high to very high. Permeability is slow. The saturated hydraulic conductivity is moderately low.
USE AND VEGETATION: Used mainly for hardwoods or red cedar. Some areas are cleared and used for grassland or urban development. Hardwoods are mainly oak and hickory. Native vegetation is warm season grasses with scattered trees.
DISTRIBUTION AND EXTENT: Ozark Highlands of Missouri and possibly Arkansas (MLRA 116A). The series is of moderate extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Morgantown, West Virginia
SERIES ESTABLISHED: Barry County, Missouri, 1990.
REMARKS: Diagnostic horizons and features recognized in this series are: mollic epipedon - the zone from the surface of the soil to a depth of 14 inches (Ap and A horizons);
argillic horizon - the zone from 14 inches to 39 inches (2Bt1, 2Bt2 and 2Bt3 horizons);
lithic contact - 39 inches.
