In ]nose places it is in long, narrow areas more than 20 acres iu size. This soil has the profile described as representative for the series. Included witl] this soil in mapping are small areas of Valmont clay loam, 1 to .^, percent slopes; Nunn clay loam, a to a percent slope=_; and Valmont cobby cla}• loam. 1 to :i percent slopes. These included soils make up abort 15 percent of each mapped area. Runoff is rapid on this soil. The erosion hazard is moderate. Al] of the acreage of this soil is used for irrigated and dn•land crops and for pasture. (Ca.pabilit}• netts IIIe- °_- irritated. and IIIe-7, nonirrigated; tree suitability group A) almont cobbly clay loam, 1 to 5 percent slopes (VcC1.-This soil is on high terraces and outwash fans in []]e west-celltra] part of the Area. In most places it is in areas more tltcl] ?0 acres in size.. The profile of this soil is much like the one described as represt•ntative for She series, but, the surface laver is abort 6 inches of cobbly clay loam. The subsoil is about 14 inches of cobbh• clai• loam or cobble clay (fig. 5). Included with this soil in mapping is a Valmont-like soil that is redder than this soil, that has less than 10 percent gral~el and cobblestones, and that contains some depressions supporting no vegetation and having a crested surface laver. Also inchtded ere small areas of `'al- mont clay loaul. a to 5 percent slopes. These included soils make up abort ]5 percent of each mapped area. Runoff is medium on this soil. The erosion hazard is slight. to moderate. This soil is not well suited to cultivation and the har- vesting of craps becanseit.has too tunny cobblestones and too much gravel on its surface. It is, however, a good grass-prodnc.ing soil. \lost of the acreage is used for native ran^e. A few small areas are used for ]mgated pasture. (Capability units Vs-1, irrigated. and ~'IIs-1, nonirrigated: tree snitAhilit.•y- group F) Valmont cobbly clay loam, 5 to 25 percent slopes IVcEI.-This soil is on the side slopes of higl] terraces or outwash fans, maim}- in the south-central part of the Area. Ill mast places it is in long, narrow areas more than ~0 Aares in size. The profile of this soil is m»ch like the one described as roprese.ntatiye for t•he se.nics, but the surface layer is about. 6 inches of cobbly clay loam. The subsoil is abort 12 inches of cobbl}• cla}• or clay loam. There are rarying amounts of grat•el and cobblestones throughout the pro- file, Included with this soil in mapping are a few small areas of a Valmont-like soil that has a layer of gravel at a depth of morn than 40 inche=. A few minor areas have shale or sandstone underlying the very grayelh• lavers within a depth of 40 inches from the surface. Also included are some small areas of Valmont cobbly clac• loam. 1 to 5 percent slopes. Included soils make rap Abort °_0 percent of each mapped area. Runoff is medium to rapid on this soil The erosion hazard is moderate to high. Figure 3~Profile of Valmont cobbly clay loam, 1 l0 5 percent slopes. All of the acreage of this soil is used for nnt.ive range. (Capability unit ~%IIs-1, nonirrigated: tree suitability group 6) Weld Series The «'cld series is made rap of deep. well-dr~2ined soils. These soils formed m] smooth uplands. mainly in loamy wind-laid parent material. Slopes are. 0 to ~ 5 percent. Elevations arc 4 q00 to :,.500 feet. Tb~~ nat.iye vegetation is mainly short grasses.
