TEKLANIKA SERIES

The Teklanika series consists of very deep, excessively drained sandy soils on dunes. Slopes range from 1 to 70 percent. Mean annual temperature is about 27 degrees F. and the mean annual precipitation is about 15 inches.

TAXONOMIC CLASS: Mixed Typic Cryopsamments

TYPICAL PEDON: Teklanika loamy fine sand - on a 9 percent slope in rolling to steep dunes. (All colors are for moist soil)

Oe--2 inches to 0; reddish brown (5YR 4/3) mat of moderately decomposed forest litter; many roots; abrupt smooth boundary.

A--0 to 4 inches; yellowish red (5YR 5/6) loamy fine sand; weak fine granular structure; very friable; common roots; very strongly acid; abrupt smooth boundary.

AC--4 to 7 inches; strong brown (7.5YR 5/6) fine sand; single grain; loose; common roots; moderately acid; abrupt smooth boundary.

C--7 to 55 inches; light olive brown (2.5Y 5/4) fine sand; single grain; loose; few grading to no roots; slightly acid.

TYPE LOCATION: Totchaket Area, Alaska; in the NW 1/4 of the SW 1/4 of the SW 1/4 of Section 9, T.6S., R.12W., Fairbanks Meridian.

RANGE IN CHARACTERISTICS: The A horizon ranges from fine sand to silt loam. Silt loam or sandy loam, where these textures occur, is less than 5 inches thick. The A horizon ranges from 10YR 4/4 to 5YR 5/6. The C horizon ranges from 2.5Y 4/2 to 2.5Y 5/4. Irregular strata of medium sand occur in the C horizon in some pedons.

COMPETING SERIES: These are the Mysten, Skagway, and Witefels series. Mysten soils are gravelly within the control section. Skagway soils are calcareous in the control section. Witefels soils have a paralithic contact within 20 to 40 inches.

GEOGRAPHIC SETTING: Teklanika soils occupy rolling to steep dunes associated with outwash plains in interior Alaska. Slopes are irregular and range from 1 to 70 percent. The mean annual temperature ranges from 24 to 30 degrees F., and the mean annual precipitation from 10 to 20 inches.

GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dotlake and Nenana soils. Dotlake soils are in swales between dunes, and are strongly mottled and underlain by permafrost. Nenana soils are on low dunes and outwash plains, and have a brown silty cambic horizon.

DRAINAGE AND PERMEABILITY: Excessively drained. Runoff is rapid when frozen or saturated, medium to slow when dry. Rapid permeability.

USE AND VEGETATION: Native vegetation is forest of white spruce, paper birch, and quaking aspen. The soils are presently unused, but are suitable for logging.

SERIES ESTABLISHED: Totchaket Area, Alaska, 1978.

REMARKS: The Teklanika soils were originally included with the Beales series, which are now restricted to soils with a thin cambic horizon and formed in a loess mantle over eolian sand.
