(0 to 8 inches thick)
C4--24 to 60 inches; yellowish red (5YR 5/6) very gravelly sandy loam, yellowish red (5YR 4/6) moist; massive; loose; few very fine roots; common coarse interstitial pores; 60 percent pebbles and 5 percent cobbles; strongly calcareous; moderately alkaline (pH 8.0).
TYPE LOCATION: Kane County, Utah; Ponderosa Canyon; NW 1/4 of sec. 16, T. 38 S., R. 4 W.
RANGE IN CHARACTERISTICS: Rock fragments in the particle-size control section average 35 to 50 percent. The mean annual soil temperature is about 44 to 47 degrees F., and the mean summer soil temperature at depths of 20 inches is about 49 to 64 degrees F. The organic matter content appears to decrease irregularly with depth. These soils are noncalcareous to strongly calcareous in the A horizon and moderately calcareous or strongly calcareous in the C horizons.
The A horizon has hue of 5YR to 10YR, value of 5 or 6 dry, 3 or 4 moist and choma of 2 to 4.
The C horizon has hue of 5YR to 10YR, value of 5 to 7 dry, 4 to 6 moist and chroma of 2 to 6. It is stratified gravelly and very gravelly loamy sand, gravelly and very gravelly sandy loam, sandy loam, loamy sand and gravelly loam.
COMPETING SERIES: There are no other series in the family. Series in similar families are the Hyam, Neto and Shupert series. Hyam, Neto and Shupert soils have less than 35 percent rock fragments between depths of 10 and 40 inches. Also, Shupert soils have more than 18 percent clay in the particle-size control section.
GEOGRAPHIC SETTING: Winetti soils are on long, narrow, gently sloping bottoms or valleys and strongly sloping toeslopes at elevations of 7,100 to 8,000 feet. They formed in mixed alluvium from sandstone, limestone and shale. Slope gradients are 0 to 8 percent. The average annual precipitation is 12 to 18 inches and the freeze-free period ranges from 80 to 100 days. The mean annual temperature is 42 to 45 degrees F., and the average summer temperature is 59 to 64 degrees F.
GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Neto and Shupert soils.
DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately rapid permeability.
USE AND VEGETATION: Winetti soils are used for rangeland, wildlife and some timber production. The potential vegetation is ponderosa pine, white fir, Douglas-fir, pinyon pine, juniper, bitterbrush, Gambel oak, curlleaf mountainmahogany, currant, Kentucky bluegrass, needleandthread, slender wheatgrass, and Indian ricegrass.
DISTRIBUTION AND EXTENT: These soils are in the south-central part of Utah. They are not extensive.
MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana
SERIES ESTABLISHED: Kane County (Paunsaugunt Soil Survey Area), Utah, 1969.
REMARKS: These soils were formerly classified as Alluvial soils.
Diagnostic horizon and features recognized in this pedon are:
Ochric epipedon - the zone from the surface of the soil to 4 inches (A horizon)
Fluvent feature - on irregular decrease in organic matter
Ustic feature - the soil moisture control section is dry in some or all parts for 90 or more cumulative days in most years but is not dry in all parts more than half the time that the soil temperature at 20 inches is above 41 degrees F.
The superactive cation exchange activity class was added in 03/2003 to the taxonomic classification by the National Soil Survey Center on request of the Lakewood MLRA office, without review of the soil series property data. The remainder of this document has not been updated.
