feet of the surtace. Quaternary age deposits, which are also present in the study area, consist of wind <br />• deposited material, stream lain alluvium, and local slopewash. See Section 2.04.6, Geology Description for <br />a more detailed discussion of the geology for the study and surrounding areas. <br />Soil - 1987. The dominant soils within the study area are the Barx, Progresso,. Bond, Bowdish, Lazear, <br />Travessilla, and Pinon (sic) series. Also included are large areas of Haplaquolls (no series names assigned). <br />The Barx, Progresso, and Bond series are the predominant cropland soils and were originally dominated by <br />sagebrush-grassland native vegetation prior to cultivation. The Barx series consists of deep well drained <br />sandy loam soils on flat to gently sloping uplands formed in alluvium derived from sandstone. The Bond and <br />Progresso series consist of shallow to moderately deep well drained sandy loam soils on uplands formed in <br />alluvium derived from sandstone. Mixed with the above soils are smaller Inclusions of Lazear and Bowdish <br />sandy clay looms. These upland soils are shallow to moderately deep, well drained, and were formed in <br />residuum derived from sandstone and interbedded shales. The Travessilla and Pinon channery sandy loam <br />soils occur on uplands that cannot be cropped or irrigated because of rock outcrops, shallow soils, and <br />topography. These areas have a sagebrush-grass/forb vegetation cover, but the original native vegetation <br />was dominated by pinyon-juniperwith associated understory shrubs and herbaceous species. The Travessilla <br />and Pinon channery sandy looms are shallow to very shallow well drained soils formed from sandstone. In <br />terms of agriculture, the latter two soils are the poorest in the study area. Other soils found on~the study area <br />• include the Haplaquolls (no series name assigned). These are poorly drained shallow to deep soils and range <br />from silty clay looms to sandy looms. They have formed in alluvium from recently deposited sediments in <br />minor intermittent streams, sloughs, flood plains, and seepy areas below areas of ground water discharge. <br />The Haplaquoll soils would most probably not be represented in the area if not for the large amounts of <br />supplemental water provided by irrigation activities. See Section 2.04.9, "Soil Resources Information," for a <br />detailed soils discussion. <br />Soil - 1999. In 1998 a new Order I Soil Survey was conducted by Intermountain Resource Inventories Inc. <br />(IRI), Jim Irvine principal investigator. The survey covered lands and properties outlined in the beginning of <br />this chapter. <br />Soil consisted of 8 soil map units with a total of 10 soil types. Soil ranged from deep to shallow with underlying <br />bedrock being soft to hard. Deepersoils formed in aeolian deposits and underlying residuum. Moderately deep <br />to shallow soils formed in residual parent material. Barx soil is predominantly in hayland or irrigated pastures. <br />Bowbac, Bowdish and Darvey soils are predominantly irrigated pasture with some haylands.
