TYPE LOCATION: Clinton County, New York; in the town of Ellenburg, about 400 feet north of intersection of Bohen Road and NY Route 190, and 120 feet east of Bohen Road; USGS Churubusco NY topographic quadrangle; Latitude 44 degrees, 52 minutes, 33 seconds N. and Longitude 73 degrees, 57 minutes, 43 seconds W. NAD 1927.
RANGE IN CHARACTERISTICS: Thickness of the solum ranges from 21 to 40 inches. Depth to bedrock is 20 to 40 inches. Redoximorphic features consisting of Fe and clay depletions, and concentrations of Fe-Mn oxides occur within 16 inches of the mineral soil surface. Rock fragments, dominantly of sandstone and granite, range from 5 to 35 percent by volume throughout. Unless limed, reaction ranges from strongly acid to slightly acid in the upper solum, and moderately acid to neutral below.
The Ap horizons have hue of 10YR, value of 2 or 3, and chroma of 1 through 3. Unplowed A horizons have value of 2 or 3, and chroma of 1 or 2. Texture is fine sandy loam or loam in the fine earth fraction.
The BE horizon, if present, has hue of 7.5YR through 2.5Y, value of 4 through 6 and chroma of 2 through 4. It has faint or distinct redox depletions or concentrations. Texture is fine sandy loam or loam in the fine earth fraction. Structure is weak or moderate subangular blocky or platy. Consistence is friable or very friable.
The Bw horizons have hue of 7.5YR through 2.5Y, value of 4 through 6 and chroma of 2 through 4, and has faint or distinct redox depletions or concentrations. Texture is fine sandy loam or loam in the fine earth fraction. Structure is weak or moderate subangular blocky or prismatic. Consistence is friable but may be firm in place.
The Bg horizon has hue of 10YR or 2.5Y, value of 4 through 6 and chroma of 0 through 2. Faint or distinct redox depletions or concentrations are absent to many. Texture is fine sandy loam or loam in the fine earth fraction. Structure is weak or moderate subangular blocky or platy. Consistence is friable or very friable.
The BC horizon, if present, has hue of 10YR or 2.5Y, value of 3 through 6 and chroma of 2 or 3 with faint or distinct redox depletions or concentrations. Texture is sandy loam, fine sandy loam or loam in the fine earth fraction. Structure is weak or moderate platy, prismatic or subangular blocky. Consistence is friable but may be firm in place.
The C horizon, if present, has hue of 10YR or 2.5Y, value of 4 through 6 and chroma of 2 through 4 with faint or distinct redox depletions or concentrations. Texture is sandy loam, fine sandy loam or loam in the fine earth fraction. Structure is weak or moderate platy, or it is massive. Consistence is friable but may be firm in place.
COMPETING SERIES: These include the Jacobsville, Mino, Minnow (T), and Peasleeville series in the same family. Jacobsville and Minnow (T) are not located in Region R. Mino and Peasleeville soils have bedrock at depths greater than 40 inches.
The Brayton, Cowhorn, Ensley, and Monarda soils are in related families. Brayton and Monarda soils have dense basal till substrata and are very deep. Cowhorn and Ensley soils have bedrock at depths greater than 40 inches.
GEOGRAPHIC SETTING: The Chazy soils are nearly level and gently sloping soils on uplands. Slope ranges from 0 to 8 percent. They are in slight depressions and in areas between sandstone bedrock ridges. The till parent material is derived mainly from sandstone and granite, but also may contain fragments of other sedimentary rock such as dolomite. Mean annual precipitation ranges from 32 to 36 inches. Mean annual air temperature ranges from 41 to 45 degrees F. Mean frost-free season ranges from 90 to 140 days. Elevation ranges from 200 to 1800 feet above sea level.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the Conic, Irona, Lyonmounten, Peasleeville, Schroon, Sunapee and Topknot soils. The well drained Conic soils are in a drainage sequence. The Irona and Topknot soils are on similar landscape, but are 10 to 20 inches to sandstone bedrock. The Peasleeville and Lyonmounten soils are also on similar landscape but are very deep to bedrock. Moderately well drained Schroon and Sunapee soils occur on nearby more convex landscapes and are very deep.
DRAINAGE AND PERMEABILITY: Somewhat poorly drained. The potential for surface runoff is negligible to very high. Permeability is moderate.
USE AND VEGETATION: Many areas are in woodland or reverting to brush. Areas cleared of stones or boulders are used mainly for pasture or hay. Wooded areas contain red maple, eastern white pine, northern white cedar, quaking aspen or gray birch.
DISTRIBUTION AND EXTENT: Champlain and St. Lawrence Valley of Northern New York. MLRA 142. The series is of small extent.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Amherst, Massachusetts
SERIES ESTABLISHED: Clinton County, New York, 1995
REMARKS: This represents a partial update of the series to Established. Not all items were reviewed at this time. CEC activity class is added as active based on data from associated soils in similar parent materials.
Diagnostic horizons and other features recognized in the typical pedon are:
1) Ochric epipedon - from 0 to 10 inches (Ap horizon).
2) Cambic horizon - from 10 to 28 inches (Bw and Bg
horizons).
3) Aeric subgroup - color value and chroma of 3 or more
in a horizon between the Ap and 30 inches.
4) Redoximorphic Features - Fe and clay depletions, and
Fe concentrations (Bw and Bg horizons).
