_____ 18 to 33 cm; reddish brown (5YR 5/4) gravelly sandy clay loam; moderate medium subangular blocky structure; firm; common fine roots; common, distinct clay films; 18 percent fine rounded and sub-rounded quartzite, gneiss, and granite gravel; 5 percent quartzite cobbles; moderately acid; clear smooth boundary.

_____ 33 to 52 cm; red (2.5YR 5/6) clay; strong fine and medium subangular and angular blocky structure; very firm; few fine roots; many, distinct clay films; 2% quartzite and gneiss gravel; slightly acid; abrupt smooth boundary.

_____ 52 to 88 cm; strong brown (7.5YR 4/6) light sandy clay loam; 25% pockets of yellowish brown (10YR 5/6); weak, coarse, subangular blocky structure; friable, slightly sticky, slightly plastic; few fine roots; few, faint clay films; 5 percent quartzite in veins; 20% rock-controlled structure; slightly acid; clear smooth boundary.

_____ -- 88-99 cm; light yellowish brown (10YR 6/4) loamy coarse sand; few fine faint (10YR 6/2) redox depletions and few fine distinct 10YR 5/6 concentrations of Fe; structureless, massive; very few fine roots; 5 percent quartzite in veins; 70% rock-controlled structure; abrupt wavy boundary.

_____-- 99-125+ cm; strongly cemented granite bedrock that cannot be dug with a spade. Few thin quartzite veins.

NOTE: quartzite in veins is proof-positive the PM is metamorphic or igneous residuum.

8. Clarksville Series
Physiography: Triassic Basin Landuse: pasture
Landscape position: convex upland summit Elevation (ft.): 1105
Parent material: residuum from sedimentary rocks Aspect: 333º
Slope gradient (%): 1.5 Perched water table
Drainage class: somewhat poorly drained

_____--0 to 17 cm; dark grayish brown (7.5Y 4/2) sandy loam; weak medium granular structure; friable; many fine and medium roots; 1 percent fine pebbles; slightly acid; clear smooth boundary.

_____--17 to 44 cm; dark grayish brown (7.5YR 6/3) sandy loam; moderate medium subangular blocky structure; friable; many fine and medium roots; many medium (2 to 4 mm) black concretions; neutral; clear wavy boundary.

_____--44 to 66 cm; brown (7.5YR 4/4) clay; few fine distinct dark grayish brown (2.5Y 4/2) redox depletions; moderate medium subangular and angular blocky structure; very firm; many fine and medium roots; common distinct clay films on faces of peds; common slickensides; common black Mn stains on ped surfaces; slightly acid; gradual smooth boundary.

_____ --66 to 97 cm; brown (7.5YR 4/4) clay; common medium distinct very pale brown (10YR 7/3) and few fine distinct dark grayish brown (2.5Y 4/2) redox depletions; moderate medium and coarse angular blocky structure; very firm; many fine and medium roots along faces of peds; common distinct clay films on faces of peds; common slickensides and pressure faces (shiny ped surfaces); common black Mn stains on ped surfaces; neutral; clear wavy boundary.

_____--97 to 112 cm; dark red (2.5YR 3/4) sandy loam saprolite with very pale brown (10YR 6/3), and yellowish brown (10YR 6/6) mottles; structureless, massive; few fine roots that follow bedding planes; common thick Mn stains on weathered former bedrock planes; neutral; clear wavy boundary.

_____--112 to 200 cm; dark maroon, strongly cemented, sandstone with few mica flakes; common thick Mn stains on planes between rock surfaces.

NOTE: mottles = redox features. If yellower, more orange, or redder than matrix = concentration of Fe. If blackened = Mn + Fe concentration. If lower chroma and/or higher value than matrix = depletion. Only depletions with both V > 4, C < 2 indicate water tables until research proves otherwise. NOTE: Sedimentary rock is often thinly bedded, so a mix of logically-related bedrock frags is not unexpected for residuum, unless the soil is located where transportation of PM is expected, the upper horizons have mixtures that do not match the bedrock beneath, and/or the lowermost horizon/s have bedrock frags that match the bedrock layer beneath exactly. Chert is a SiO2 impurity left behind when limestone/dolomite weathers away, quartzite is a SiO2 when metamorphic or igneous weathers away, so those are expected to remain behind in the soil.
