TYPE LOCATION: Navajo County, Arizona; on the south side of Egglofstein Butte; 700 feet west and 1000 feet north of the southeast corner of section 16, T. 25 N., R. 18 E.
RANGE IN CHARACTERISTICS:
Soil moisture - Intermittently moist in some part of the soil moisture control section during July-September and December-February. Driest during May and June. Typic aridic soil moisture regime.
Rock fragments - Averages 5 to 35 percent in the particle size control section, but individual horizons range to 55 percent
Soil Temperature: 54 to 58 degrees F.
Depth to calcic horizon: 6 to 30 inches
Organic matter content: Less than 1 percent
Reaction: Slightly to strongly alkaline
Calcium carbonate: 5 to 30 percent calcium carbonate equivalent in the calcic horizon
Stratification- Many pedons have discontinuous lenses of sandy material with highly variable gravel content at depths of 20 to 40 inches
A horizon
Hue: 7.5YR, 5YR, 2.5YR
Value: 4, 5, or 6 dry, 3, 4 or 5 moist
Chroma: 3 thorough 6, dry or moist
B horizon
Hue: 7.5YR, 5YR, 2.5YR
Value: 3 through 6 dry, 3 through 6 moist
Chroma: 3 through 6, dry or moist
Texture: loamy fine sand, sandy loam, fine sandy loam, very fine sandy loam, or loam. May include sand or fine sand in the lower part
Some pedons have C or buried B horizons with clay, clay loam, sandy clay loam, sand, fine sand, loamy fine sand, or fine sandy loam textures at depths of 40 inches or more.
COMPETING SERIES: These are the Bluechief (UT), Boreham (UT), Hiko Springs (UT), Kaito (AZ), McCutchen (NV), Moffat (UT), Nakai (UT), Nakoy (UT), Nolava (UT), Nuahs (NV), Pagina (AZ), Riemod (UT), Teabrush (T)(UT), and Trook series. Bluechief and Pagina soils have bedrock at depths of 20 to 40 inches. Boreham and Nolava soils have more than 18 percent total clay in the control section. McCutchen soils have hue yellower than 7.5YR and are high in pyroclastic materials. Moffat and Nakai soils have less gravel and have Bw horizons. Nuahs soils have yellower hue. Boreham, Nakoy, Nolava, Riemod, Teabrush, and Trook soils have soil temperatures less then 52 degrees F. Kaito soils have bedrock at depths of 40 to 60 inches. Riemod soils have accumulations of gypsum. In addition, Hiko Springs, McCutchen, and Nuahs soils are in the Great Basin Desert (MLRAs 28A, 28B, 29) and have precipitation more evenly distributed throughout the year.
GEOGRAPHIC SETTING: The Kinan soils are on plateaus and fan terraces. They formed in stratified eolian deposits and fan alluvium from sedimentary rocks. Slopes are l to l5 percent. Elevations are 3500 to 6000 feet. Mean annual precipitation is 6 to 11 inches, occurring as summer thunderstorms and gentle winter rain and snow. Mean annual air temperature is 52 to 57 degrees F. The frost-free period is 130 to 180 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Monue, Nakai, Pennell, Sheppard and Strych series. Monue and Nakai soils are adjacent and slightly lower on the landscape and have less than 15 percent rock fragments. Monue soils lack calcic horizons. Pennell soils are slightly higher and are shallow over bedrock. Sheppard soils are adjacent and sandy throughout. The loamy-skeletal Strych soils are adjacent and slightly higher on the landscape.
DRAINAGE AND PERMEABILITY: Somewhat excessively drained; slow runoff; moderately rapid permeability.
USE AND VEGETATION: Used mainly for livestock grazing and wildlife habitat. Vegetation is mainly galleta, blue grama, black grama, Indian ricegrass, Cutler Mormontea, and needleandthread.
DISTRIBUTION AND EXTENT: Northern Arizona. This series is of moderate extent. MLRA 35.
