Order l Soil Survey, New Horizon Mine
<br />COMPETING SERIES: These are the Hiland and Solirec series. Hiland soils have
<br />less than 15 percent carbonates in the calcic horizon. Solirec soils are in MLRA 34
<br />and receive maximum precipitation in sprang and fall. Similar soils and previously
<br />competing series are (Ustic Haplargids) Bowback, Cambria, Cushman, Decdlney,
<br />Fcrkwood, Fcrt, Maysdorf, Pugsley, Teckla, Yenlo and (Ustollic Haplargids) Balon,
<br />Buckle, Cerrillos, Clovis, Fatkig, Fernando, Flaco, Gaddes, Gapbutte, Hagerman,
<br />Harboard, Los Alamos, Millett, Celop, Olney, Palacid, Penistaja, Pokemen, Potts,
<br />Progresso, Quagwa, Redpen, Scholle, Selpats, Spangler, Spenlo, Sundance, Tapia,
<br />Tlhreetop, Toluca, and Tuweep. Only Cerrillos, Clovis, Fernando, Millett, Scholle,
<br />Tapia, Toluca, and Tuweep soils are reclassified to Calciargids under the nth
<br />Edition. Cerrillos soils are dryest from October to May. Clovis sails receive more
<br />than half of their precipitation between the months of July and October, Fernando
<br />soils contain 50 to 80 percent silt in the salum and are in MLRA 51. Millett soils
<br />contain 25 to 75 percent gravel and cobbles in the lower part of the solum. Scholle
<br />sc)ils contain 15 to 35 percent gravel in the control section. Tapia soils contain
<br />caliche fragments in the Bt and Bk horizons. Toluca sails are in MLRA 58A and are
<br />yellower than 5YR throughout. Tuweep soils are yellower than 5YR and formed in
<br />alluvium from pyroclastics and basalt.
<br />GEOGRAPHIC SETTING:
<br />Parent material: reworked eoliarn rinaterial and alluVurr derived from sandstone
<br />Landform; alluvial fans, terraces, hills, and mesas
<br />Slopes: 0 to 15 percent
<br />Llevation_ 4,400 to Y,800 feet
<br />Mean annual temperature: 45 to 55 degrees F
<br />Mean annual precipitation: 0 to 14 inches
<br />Precipitation is fairly evenly distributed throughout the year with July and August
<br />being slightly wetter and June being slightly dryer.
<br />Frost -free period: 100 to 175 days
<br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Abra Bega ,
<br />Mivida Rizno Sazi Strych and Windwhistle soils, Abra soils lack an horizon of clay
<br />accumulation. Begay and Mivida soils have coarse -loamy particle size control
<br />sections. Sazi and Windwhistle soils have bedrock at a depth of 20 to Ott inches
<br />deep. Strych soils have more than 35 percent rock fragments in the particle size
<br />control section.
<br />DRAINAGE AND PERMEABILITY: well drained, negligible to high runoff,
<br />moderate or moderately slow permeability
<br />USE AND VEGETATION: These soils are used mainly for rangeland, The
<br />potential vegetation is Indian rcegrass, galleta, Wyoming big sagebrush, and
<br />winterfat.
<br />DISTRIBUTION AND EXTENT: Southeast Utah and southwest Colorado. LRR
<br />D, MLRA 34, 35, 39. This series is of moderate extent.
<br />MLRA OFFICE RESPONSIBLE: Phoenix, Arizona
<br />SERIES ESTABLISHED Utah- Central Part, Grand County, Utah 1985. The
<br />name comes from the 'Bar X wash.
<br />REMARKS: Diagnostic horizons and features recognized in this pedon are:
<br />ochric epipedcn: The zone from 0 to 3 inches. (A)
