TYPE LOCATION: Okanogan County, Washington; about 3 miles northwest of the town of Monse; 75 feet west and 50 feet north of the southeast corner of the SE1/4 NE1/4 sec. 20, T.31N., R.25E. (latitude 48 degrees, 10 minutes, 17.32 seconds north, longitude 119 degrees, 42 minutes, 44.79 seconds west).
RANGE IN CHARACTERISTICS:
Soil Moisture: These soils are usually dry in all parts for more than half the time when the soil temperature is greater than 41 degrees F (105 to 115 days); aridic moisture regime.
Soil Temperature: The mean annual soil temperature is 47 to 55 degrees F.
Rock Fragments: 0 to 10 percent coarse fragments in the upper and lower parts of the particle-size control section
Depth to lithologic discontinuity: 21 to 38 inches.
Reaction: slightly acid to slightly alkaline.
Soil Texture: The upper part is fine sandy loam or sandy loam with 30 to 50 percent sand coarser than very fine sand.
Mollic epipedon: 7 to 20 inches thick.

COMPETING SERIES: These are the Leavers and Pogue series. Leavers soils have few clay films and are dry for more than 115 consecutive days. Pogue soils have more than 35 percent rock fragments in the lower part of the particle-size control section.
GEOGRAPHIC SETTING: Aeneas soils are on outwash terraces. Slope ranges from 0 to 15 percent. The soils formed in glacial outwash. Elevations are 800 to 1,900 feet. The climate is characterized by warm, dry summers and cool, moist winters. The average annual precipitation is 9 to 12 inches. The mean January temperature is about 22 degrees F, the mean July temperature is about 73 degrees F, and the mean annual air temperature is about 49 degrees F. The frost-free season is 140 to 190 days.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Cashmere, Cashmont, Ellisforde, Ewall, Farrell, Haley, Okanogan, Peshastin, Quincy, Skaha, and Strat soils and the competing Pogue soils. Cashmere, Cashmont, Farrell, and Okanogan soils are coarse-loamy. Ellisforde soils are coarse-silty. Ewall and Quincy soils are sandy. Haley soils have a xeric moisture regime. Peshastin and Strat soils are loamy-skeletal. Skaha soils are sandy-skeletal.
DRAINAGE AND PERMEABILITY: Well drained; runoff is slow to medium; permeability is moderately rapid over rapid.
USE AND VEGETATION: Principal uses are cropland, livestock grazing and wildlife habitat. Dryland small grains and irrigated tree fruit, hay and pasture are common crops. The native vegetation is bluebunch wheatgrass, Sandberg bluegrass, arrowleaf balsamroot, snow eriogonum, antelope bitterbrush, lupine, yarrow, and big sagebrush.
DISTRIBUTION AND EXTENT: North-central Washington; MLRA 8. The soils are of small extent.
