C1--13 to 30 centimeters; stratified brown (10YR 5/3) and pale brown (10YR 6/3) cobbly fine sand and pale brown (10YR 6/3) and dark grayish brown (10YR 4/2) cobbly silt loam; massive; very friable; about 15 percent cobbles; neutral; clear smooth boundary. (0 to 38 centimeters thick)
C2--30 to 152 centimeters; stratified dark grayish brown (10YR 4/2), brown (10YR 5/3) and pale brown (10YR 6/3) very cobbly silt loam, very cobbly fine sandy loam, and very cobbly fine sand and very cobbly sand; massive; very friable; about 15 percent pebbles and 40 percent cobbles, mostly dolomite; neutral.
TYPE LOCATION: Major Land Resource Area (MLRA) 105-Northern Mississippi Valley Loess Hills, Houston County, Minnesota; located about 4 miles east of Caledonia, Minnesota; about 1200 feet south and 1200 feet west of the northeast corner of section 22, T. 102 N., R. 5 W. USGS Caledonia topographic quadrangle; latitude 43 degrees, 37 minutes, 38 seconds N. and longitude 91 degrees, 25 minutes, 0 seconds W. NAD 83.
RANGE IN CHARACTERISTICS:
Thickness of loamy mantle--13 to 51 centimeters;
Depth to free carbonates--typically absent to depths of 102 centimeters or more, but are at depths as shallow as 51 centimeters in some pedons
Content of clay in the particle-size control section (weighted average)--5 to 18 percent
Rock fragment content--cobbles and gravel cover 0 to 50 percent of the surface; 5 to 35 percent in the loamy mantle, mostly pebbles and cobblestones; the C horizon contains 35 to 75 percent coarse fragments, mostly pebbles and cobblestones; coarse fragments consist of sandstone, dolomite, and limestone
A horizon:
Hue10YR
Value--3 through 5; 4 or more when the upper 18 centimeters is mixed
Chroma--2 or 3
Texture--fine sandy loam, very fine sandy loam, loam, or silt loam or their cobbly analogs. Thin, finer, or coarser textured strata are in many pedons
Reaction--slightly acid or neutral
C horizon:
Hue--10YR or 2.5Y
Value--3 through 6
Chroma--2 through 4
Texture--stratified textures of sand, loamy sand, sandy loam, loam, or silt loam with 15 to 75 percent coarse fragments.
Reaction--neutral or mildly alkaline.
A buried soil is below depths of 102 centimeters in some pedons.
COMPETING SERIES: These are the
Beanblossom,
Bloomsdale, and
Elsah series.
Beanblossom, Bloomsdale, and Elsah--all have a warmer climate. In addition, Beanblossom--are more acid in the control section;
Bloomsdale--have more clay in the control section;
Elsah--contain more silt and less sand.
GEOGRAPHIC SETTING:
Parent Material-- loamy-skeletal colluvium and alluvium.
Landform-- flood plains along the upper reaches of streams with high velocities and on alluvial fans at the mouths of drainageways that dissect very steep hill slopes
Slope--1 to 15 percent
Elevation200 to 400 meters above sea level
Mean annual precipitation711 to 864 millimeters
Mean annual air temperature8 to 11 degrees C
Frost-free period145 to 205 days
GEOGRAPHICALLY ASSOCIATED SOILS: These are the
Arenzville,
Huntsville, and
Newalbin soils on nearby flood plains.
Arenzville and Newalbin--formed in recent silty sediments. Arenzville soils are moderately well and well drained and Newalbin soils are poorly and very poorly drained
Huntsville--have a thick mollic epipedon, and are on parts of the flood plain that have lower velocities during floods
DRAINAGE AND SATURATED HYDRAULIC CONDUCTIVITY:
Drainage class--well drained, a saturated zone does not occur within a depth of 1.8 meters during April to June in normal years
Saturated hydraulic conductivity--14.1-42.3 micrometers per second (moderately rapid) throughout
Surface runoff potentialmedium
Floodingoccassional to frequent flooding for very brief duration
USE AND VEGETATION: Most of these soils are in pasture and forest. Native vegetation is deciduous forest.
DISTRIBUTION AND EXTENT:
Physiographic division--Interior Plains
Physiographic Province--Central Lowland
Physiographic sections--Wisconsin driftless section,
MLRAs--Northern Mississippi Valley Loess Hills (105)
LRR M--southeastern Minnesota, southwestern Wisconsin, northwestern Illinois and possibly north-eastern Iowa
Extent--moderate

SERIES ESTABLISHED: Houston County, Minnesota, 1981.
REMARKS: The Beavercreek soils were mostly mapped as a miscellaneous land type in the past such as stony colluvial or alluvial land. The moderately well drained phase was removed during La Crosse County final correlation.
