the 1998 soil survey (black line) and the permit boundary (magenta line) on Map 2.04.9 -1 does not <br />have soil sample points for depth. <br />Map unit 98A (Begay fine sandy loam) occurs on alluvial terraces formed along Tuttle EreekDraw. <br />Profiles were described to 72 inches. Some areas may have soil deeper than 72 inches and yield <br />a slightly greater amount of salvage material. This unit is considered prime farmland soil as of the <br />2008 NRCS determination. <br />Map unit 98B (Valleycity - rock outcrop complex) occurs on steep mesa side slopes. Hardness of <br />bedrock varies depending on the underlying strata. Coarse fragments range from boulders to <br />cobbles and are residual and colluvial in nature. Valleycity soil has the same physical and chemical <br />properties as those soils similarly named in the survey area. Valleycity is outside the range of <br />characteristics compared to the survey area, in that it occurs in an area of 5 to 8 inches mean <br />annual precipitation. <br />Map unit 98C (Monierco fine sandy loam) occurs on mesa summits, ridges and crests. Hardness <br />of bedrock varies depending on the underlying strata. <br />Map unit 98D (Bowbac - Bowdish complex) has thinner Quaternary eolian deposits than map unit <br />98E with a mean depth to bedrock of 30 inches. These deposits have developed cambic horizons, <br />weak argillic horizons and secondary accumulations of carbonates. The accumulation of <br />carbonates is reflected in a higher pH in the Bk and Btk horizons. The pH in A, Ap, ABt, Bw and <br />Bt horizons (Lift A) averages 7.7 and in the Bk Btk and C horizons (Lift B ) averages 8.1. <br />Map unit 98E (Darvey -Barx complex) consists of areas of deep Quaternary eolian deposits. These <br />Quaternary deposits overlie Dakota Sandstone and Burro Canyon Formations with depth to <br />bedrock ranging 40 inches to greater than 72 inches with a mean depth of 53 inches. These <br />deposits have stabilized and formed cambic horizons and in some places weak argillic horizons. <br />Additionally, they have developed secondary accumulations of carbonates. The accumulation of <br />carbonates is reflected in a higher pH in the Bk and Btk horizons. The pH in A, Ap, ABt, Bw and <br />Bt horizons (Lift A) averages 7.7 and in the Bk Btk and C horizons (Lift B) averages 8.2. Soil in this <br />August 2013 (PR 08) 2.04.9 -28 <br />
