TYPE LOCATION: Rapides Parish, Louisiana; 1.1 miles west of Otis; 38 yards north of road; sec. 26, T. 3 N., R. 4 W.
RANGE IN CHARACTERISTICS: Solum thickness ranges from 40 to 60 inches.
The A or Ap horizon has hue of 10YR, value of 3 to 5, and chroma of 1 to 3. Texture is silt loam or very fine sandy loam. Reaction ranges from very strongly acid to medium acid.
The E horizon, where present, has hue of 10YR, value of 5 to 7, and chroma of 1 to 3. Texture is silt loam or very fine sandy loam. Reaction ranges from very strongly acid to medium acid.
The BE horizon, where present, has hue of 10YR, 7.5YR, or 5YR, value of 4 to 6, and chroma of 4 to 8. Texture is silty clay loam, silt loam, loam, or very fine sandy loam. Reaction ranges from very strongly acid to medium acid.
The upper part of the Bt horizon has hue of 2.5YR or 5YR, value of 3 to 5, and chroma of 4 to 8. The lower part has the same range in colors as the upper part or has hue of 10YR or 2.5Y, value of 5 or 6, and chroma of 1 or 2. Mottles in the Bt horizon are in shades of red, brown, and gray. Subhorizons of the Bt horizon have 1 or 2 chroma mottles. The Bt horizon is clay, silty clay, or silty clay loam. Reaction ranges from very strongly acid to neutral.
Color of the BC horizon is in shades of red or gray. Texture is clay or silty clay. Reaction ranges from very strongly acid to neutral.
The Bss horizon has hue of 2.5YR or 5YR, value of 4 to 6, and chroma of 4 to 6. Texture is clay. Reaction ranges from very strongly acid to moderately alkaline.
The C horizon is a reddish clay or silty clay. Reaction ranges from medium acid to moderately alkaline. Concretions of calcium carbonate range from none to common in the Bss and C horizons.
COMPETING SERIES: These are the Boswell series in the same family and the Acadia, Annona, Forbing, McKamie, and Susquehanna series. Acadia soils have 1 or 2 chroma in the argillic horizon. Annona, Forbing, and Susquehanna soils have montmorillonitic clay mineralogy. Boswell soils do not have the reddish clays in the Bss and C horizons. McKamie soils do not have 2 chroma mottles in the argillic horizon.
GEOGRAPHIC SETTING: Gore soils are on stream terraces of Pleistocene age. Dominant slopes are 1 to 5 percent but some slopes are as steep as 20 percent. These soils formed in red clayey alluvium most likely washed from Permian Red Beds and associated sediments. The climate is warm and humid. The mean annual temperature ranges from about 60 to 70 degrees F. The average annual precipitation ranges from about 45 to 60 inches.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Acadia, Forbing, and McKamie series and Morse and Muskogee series. Acadia soils are on lower, level or nearly level areas. Forbing and McKamie soils are on the slightly lower and steeper side slopes. Morse soils are on adjacent lower slopes, are calcareous throughout, and do not have 2 chroma mottles. McKamie soils are in lower areas and they have a thinner solum.
DRAINAGE AND PERMEABILITY: Gore soils are moderately well drained. Runoff is medium to very rapid. Permeability is very slow. A water table is 6 feet or more below the surface.
USE AND VEGETATION: Mostly used as woodland. Principal vegetation is mixed hardwood and pine forest. A small acreage is used as cropland or pastureland.
DISTRIBUTION AND EXTENT: Louisiana, southern Arkansas, eastern Oklahoma, and eastern Texas. This series is of moderate extent.
