The A horizon has hue of lOYR, value of 2 or 3, and chroma of 1 or 2. The Ap horizon has value
<br /> of 4 or 5 and chroma of 1 or 2 and value of 6 when dry. The E horizon has hue of lOYR, value of
<br /> 4 or 5, and chroma of 1 or 2. The A and E horizons typically are loam, silt loam, sandy loam, or
<br /> fine sandy loam, but include clay loam, if eroded. They are neutral to medium acid.
<br /> The Bt horizon has hue of lOYR in the upper part and lOYR or 2.SY in the lower part, value of 4
<br /> or 5, and chroma of 3 through 5. Mottles are present in the lower subhorizons in some pedons. It
<br /> � typically is clay loam or loam, but sandy clay loam is in parts in some pedons. The argillic
<br /> horizon has 18 to 35 percent clay and 30 to 45 percent sand. It is slightly acid to strongly acid.
<br /> Some pedons have a BC horizon.
<br /> The C horizon has a hue of lOYR or 2.SY, value of 4 or 5, and chroma of 3 through 6. It is loam
<br /> or clay loam. It lacks mottles in some pedons. It has 15 to 25 percent calcium carbonate
<br /> equivalent and is mildly or moderately alkalikne.
<br /> COMPETING SERIES: These are the Amanda, Belmo�lt, Belmore, Chenault, Cl�ili, Co��on,
<br /> Conesto<�a, Douds, EI Dara, Gallman, Grellton, Hebi-on, Hickor , High Gap, H��llin�,
<br /> Kalamaroo, Kanawha, Kendallville, Kiddei-, Kosciusko, LeRc�v, Letort, Lindle , McHeni-y,
<br /> Mandeville, Martinsville, Miami, Mifflin, Militai•y, Nc�dinc, Nordeil, Ocklev, Owosso,
<br /> Pecatonica, Princeton, Rawtioil, Relay, Renova, Richland, Riddles, Rockbridae, Roseville,
<br /> Sisson, Strawn, Summitville, Teanaw�iv, Theresa, W�iwasee, Westville, Whalan, and Woodbine
<br /> soils in the same family. Amanda horizon soils have more illite in the B and C horizon; Belmont
<br /> soils have redder hue in the B horizon. Belmore, Chili, Kalamazoo, and Ockley soils formed in
<br /> glacial outwash and have sandy or sandy-skeletal 2C horizons. Chenault soils have chert
<br /> fragments in the solum and are underlaid by limestone bedrock. Coggon, Gallman, Hickory,
<br /> Pecatonica, Renova, Riddles, Summitville, and Westville soils have thicker sola. In addition,
<br /> Coggon soils have low chroma mottles in part of the B2 horizon. Conestoga, Kendallville,
<br /> � Letort, Richland, and Rockbridge soils have more coarse fragments. Douds, El Dara, Kidder,
<br /> Sisson, and Wawasee soils have less clay and more sand or silt in the lower part of the B horizon
<br /> and in the C horizon. High Gap, Hollinger, Mandeville, Mifflin, Military, Norden, Roseville,
<br /> Whalan, and Woodbine soils have bedrock beginning between depths of 20 and 60 inches.
<br /> Grellton, Hebron, Lindley, and Rawson soils have more silt or clay or both in either the lower
<br /> part of the B horizon or C horizon or both. Kanawha soils are formed in alluvium from acid shale
<br /> and are in an area of higher rainfall. LeRoy and Strawn soils have thinner sola. McHenry and
<br /> Miami soils have more silt or clay, or both in the upper part of the solum. Martinsville soils have
<br /> redder hue in the B horizon and formed in stratified outwash or lacustrine sediments. Nodine
<br /> soils have thicker sola which is more stratified and leached of free carbonates to greater depths.
<br /> Owosso soils have more sand and less silt or clay in the upper part of their sola. Princeton soils
<br /> formed in aeolian sediments and have stratified C horizons. Relay soils have hue of 2.SY or SY
<br /> in all parts of the B horizon. Teanaway soils have firm sandy clay loam C horizons with redder
<br /> hue. Theresa soils formed partly in loess and have 2C horizons with 40 to 60 percent calcium
<br /> carbonate.
<br /> GEOGRAPHIC SETTING: Hayden soils have plane or convex slopes on gently undulating
<br /> through steep glacial moraines of the Des Moines and Grantsburg sublobe of the Late
<br />
