Some pedons are calcareous and moderately alkaline just above the bedrock.
Particle size control section (weighted average):
Clay content:18 to 35 percent
A horizon:
Hue: 5YR to 10YR
Value: 3 to 5
Chroma: N to 3
Texture: silt loam, silty clay loam, flaggy silt loam, flaggy silty clay loam, stony silt loam, or stony silty clay loam.
Clay content: 18 to 35 percent
Fragments: 0 to 35 percent by volume of limestone or chert greater than 2mm fragments and 0 to 30 percent by volume less than 2 mm in diameter and 0 to 30 percent by volume greater than 76 mm in diameter
Reaction: slightly acid to slightly alkaline
R horizon:
grayish or brownish limestone that is fractured vertically at intervals from 30 to 180 cm and the fractures range from 1 to 150 mm wide to a depth of 40 to 60 cm. The bedrock has horizontal bedding planes from 5 to 122 cm apart, but commonly are 10 to 20 cm. The bedrock is .6 meters to several meters thick.

Claremore series and
Apperson,
Catoosa,
Clarita,
Foraker,
Grainola,
Lula,
Scullin and
Westsum series. Claremore soils occur on similar areas.
pperson, Foraker, Grainola, and Westsum soils have argillic horizons, a solum more than 20 inches thick, and more than 35 percent clay content in the control section.
Apperson soils occur on broad flats and Foraker, Grainola, and
Summit soils occur on side slopes.
Catoosa, Lula and Scullin soils have argillic horizons, a solum more than 20 inches thick, and occur on similar areas.
Clarita soils have more than 35 percent clay content in the control section, cyclic properties, a solum more than 20 inches thick and occur on side slopes.
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage: Well drained
Runoff: slow to rapid
Saturated hydraulic conductivity: moderately high
USE AND VEGETATION: Mainly used for range.
In some areas the bedrock is quarried and crushed into gravel and stone for roads, masonry or riprap.
Native vegetation is short and mid grass prairie.
DISTRIBUTION AND EXTENT: In the Bluestem Hills (MLRA 76) of Oklahoma and Kansas. The series is of moderate extent.
