TYPE LOCATION: Lane County, Oregon; about 4 miles south of Florence, on the east side of Woahink Lake; in borrow pit in the NE1/4 SW1/4 SW1/4 of section 23, T. 19 S., R. 12 W.
RANGE IN CHARACTERISTICS: The soil has a udic moisture regime and has a dry period of less than 45 days during the summer. The mean annual soil temperature is 53 degrees F. The difference between the mean summer and mean winter soil temperature varies from 5 to 9 degrees F. Thickness of the solum ranges from 40 to 60 inches. The soil lacks rock fragments to a depth of 40 inches or more. Hue is 10YR to 7.5YR. It is silt loam or silty clay loam. The values of 15-bar water range from about 18 to 25 percent in individual horizons within the particle-size control section. The bulk density in the solum ranges from about .50 to .85 g/cm cubic. The umbric epipedon is 12 to 20 inches thick.
The A horizon has value of 2 or 3 moist, 4 or 5 dry, and chroma of 2 or 3 moist and dry. It has 10 to 15 percent organic matter.
The Bw horizon has value of 3 or 4 moist, 5 to 7 dry, and chroma of 3 or 4 moist and dry.
The C horizon has value of 4 to 6 moist, 6 or 7 dry, and chroma of 3 or 4 moist and dry.
COMPETING SERIES: These are the Klootchie, Neotsu, Neskowin, and Salander series. Neotso and Neskowin soils are 20 to 40 inches deep to bedrock. Salander soils have an umbric epipedon over 20 inches thick. Klootchie soils have a solum less than 40 inches thick with 15 to 35 percent gravel.
GEOGRAPHIC SETTING: Lint soils are on terraces at elevations ranging from 20 to 600 feet. Slopes range from 0 to 40 percent. These soils are formed in alluvium weathered mostly from sedimentary rocks. The climate is humid and marine in character with 60 to 80 inches of precipitation. The mean January temperature is 44 degrees F., the mean July temperature is 58 degrees F, and the mean annual temperature is 45 to 53 degrees F. The frost-free season is 180 to 240 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Bullards, Fendall, Ferrelo, and Templeton soils. Bullards and Ferrelo soils are on adjacent marine terraces and are coarse-loamy. Fendall soils are on adjacent uplands and are 20 to 40 inches deep to partially weathered shale. Templeton soils are on adjacent uplands and are fine-silty and underlain by sandstone bedrock.
DRAINAGE AND PERMEABILITY: Well drained; slow through rapid runoff; moderate permeability.
USE AND VEGETATION: Used for timber production and homesites. The timer is dominated with an overstory of Sitka spruce,Douglas fir, western redcedar, western hemlock, red alder and an understory of salal, western swordfern, vine maple, salmonberry, evergreen huckleberry, and red huckleberry.
DISTRIBUTION AND EXTENT: Coastal area of Oregon. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Portland, Oregon
SERIES ESTABLISHED: Lincoln County, Oregon, 1975.
REMARKS: This draft reflects a change in classification from Medial, isomesic Typic Dystrandepts to Medial, isomesic Alic Fluvudands. This reclassification is based on addition of the Andisol Order to Soil Taxonomy.
Diagnostic horizons and features in this pedon include:
Umbric epipedon - from 2 to 18 inches (A1, A2, and AB horizons).
Cambic horizon - from 18 to 44 inches (Bw1 and Bw2 horizons).
Medial- solum dominated by andic soil properties.
All diagnostic horizons and features are measured from the top of the first mineral horizon.
ADDITIONAL DATA: Characterization data for two profiles S72 Oreg. 10-1(1-6) and S72 Oreg. 20-1(1-7) by SCS Riverside Laboratory reported in computer printouts.
