TYPE LOCATION: McKenzie County, North Dakota; 1,675 feet west and 610 feet south of the NE corner of sec. 2, T. 146 N., R. 102 W. Latitude 47 degrees, 30 minutes, 4 seconds north and Longitude 103 degrees, 38 minutes, 21 seconds west. Burning Mine Butte, ND Quadrangle.
RANGE IN CHARACTERISTICS:
Soil temperature - 44 to 46 degrees F.
Moisture control section - between 4 and 12 inches.
Some pedons have an ABk horizon.

The calcic horizon is within a depth of 16 inches.
A horizon - Hue: 10YR or 2.5Y
Value: 4 or 5; 3 moist
Chroma: 2 or 3
Texture: silt loam
Clay content: 18 to 27 percent
Reaction: pH 7.4 to 8.4
Bk horizons - Hue: 10YR or 2.5Y
Value: 5,6 or 7; 4 or 5 moist
Chroma: 2, 3 or 4
Texture, less than 2 mm: silt loam or silty clay loam
Clay content: 18 to 35 percent
Rock fragments: 0 to 5 percent pebbles
Calcium carbonate equivalent: 15 to 40 percent
Reaction: pH 7.9 to 8.4
C horizon - Hue: 10YR or 2.5Y
Value: 6 or 7; 4 or 5 moist
Chroma: 2, 3 or 4
Texture: less than 2 mm: silt loam, silty clay loam, or very fine sandy loam. Silty clay is allowed below a depth of 60 inches.
Clay content: 18 to 35 percent (above a depth of 60 inches)
Rock fragments: 0 to 5 percent pebbles

COMPETING SERIES: Burgraff - has a paralithic contact above a depth of 40 inches.
GEOGRAPHIC SETTING:
Landform - alluvial fans and terraces.
Elevation -2,000 to 3,400 feet.
Parent material - calcareous silty alluvial deposits.
Slope- 0 to 9 percent.
Climate - long, cold winters; moist springs, warm summers.
Mean annual precipitation - 14 to 16 inches.
Mean annual air temperature - 39 to 45 degrees F.
Frost-free period - 120 to 130 days (based on 32 degrees F and 50 percent probability).
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Burgraff soils and the Boxwell, Cabbart and Floweree soils. Burgraff, Boxwell and Cabbart soils occur on nearby uplands and Floweree soils occur on similar positions as Haydraw soils. Boxwell soils are moderately deep and Cabbart soils are shallow to soft bedrock. Floweree soils have a cambic horizon and do not have a calcic horizon.
DRAINAGE AND PERMEABILITY: Well drained; moderately slow permeability; runoff is negligible to medium depending on slope.
USE AND VEGETATION: Haydraw soils are used mainly for growing small grains and for range. Potential native vegetation is mainly western wheatgrass, blue grama, bluegrass, needleandthread and fringed sagewort.
DISTRIBUTION AND EXTENT: Haydraw soils are of small extent in western North Dakota, and possibly northwestern South Dakota and eastern Montana.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Denver, Colorado.
SERIES ESTABLISHED: McKenzie County, North Dakota, 2003.
REMARKS: Diagnostic horizons and features recognized in this pedon are: mollic epipedon - the zone from the surface of the soil to a depth of 7 inches after mixing (A and Bk1 horizons); calcic horizon - the zone from 6 to 41 inches (Bk1, Bk2 and Bk3 horizons); particle-size control section - 10 to 40 inches (Bk1, Bk2 and Bk3 horizons). Haydraw soils have a frigid temperature regime and an Aridic-Ustic moisture regime.
