The A horizon has hue of 10YR, 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 10YR, 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 10YR in the upper part and 10YR or 2.5Y 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 10YR or 2.5Y, 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, Belmont, Belmore, Chenault, Chili, Coggon,
<br /> Conestoga, Douds, El Dara, Gallman, Grellton, Hebron, Hickory, High Gap, Hollinger,
<br /> Kalamazoo, Kanawha, Kendallville, Kidder, Kosciusko, LeRoy, Letort, Lindley, McHenry,
<br /> Mandeville, Martinsville, Miami, Mifflin, Military, Nodine, Norden, Ockley, Owosso,
<br /> Pecatonica, Princeton, Rawson, Relay, Renova, Richland, Riddles, Rockbridge, Roseville,
<br /> Sisson, Strawn, Summitville, Teanaway,Theresa, Wawasee,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, Letort,
<br /> Richland, and Rockbridge soils have more coarse fragments. Douds, El Dara, Kidder, Sisson, and
<br /> Wawasee soils have less clay and more sand or silt in the lower part of the B horizon and in the C
<br /> horizon. High Gap, Hollinger, Mandeville, Mifflin, Military, Norden, Roseville, Whalan, and
<br /> Woodbine soils have bedrock beginning between depths of 20 and 60 inches. Grellton, Hebron,
<br /> Lindley, and Rawson soils have more silt or clay or both in either the lower part of the B horizon
<br /> or C horizon or both. Kanawha soils are formed in alluvium from acid shale and are in an area of
<br /> higher rainfall. LeRoy and Strawn soils have thinner sola. McHenry and Miami soils have more
<br /> silt or clay, or both in the upper part of the solum. Martinsville soils have redder hue in the B
<br /> horizon and formed in stratified outwash or lacustrine sediments. Nodine soils have thicker sola
<br /> which is more stratified and leached of free carbonates to greater depths. Owosso soils have more
<br /> sand and less silt or clay in the upper part of their sola. Princeton soils formed in aeolian
<br /> sediments and have stratified C horizons. Relay soils have hue of 2.5Y or 5Y in all parts of the B
<br /> horizon. Teanaway soils have firm sandy clay loam C horizons with redder hue. Theresa soils
<br /> formed partly in loess and have 2C horizons with 40 to 60 percent calcium 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 /> Wisconsinan glaciation. Their slopes range from 2 to 40 percent and mostly are 80 to 300 feet in
