• phosphorus. It appazently has been formed from alluvial deposits of material from higher <br />~ regions. There is a small area of number 1 soil that has had its vegetation burned off several <br />years ago, but this has not modified the soil significantly. All of the area of soil 1 type is a <br />good soil and should be considered for remedial purposes. <br />Number 2 soils are also quite good in quality and should be a part of remedial efforts. There <br />aze several areas of this soil and are a Meadow silty clay loam a typic Haplorgid. Vegetation <br />on this soil is primarily various grasses, and the soil is slightly finer in texture than the <br />Woodlands silt loam. It is also deep, and contains little salt. <br />The soils represented by number 3 are also deep and are restricted to canes primarily along road <br />cuts which may have influenced their formation in recent years by exposing them to the <br />elements. They extend for short distances from the road and are accompanied by rock <br />fragments. They are part of the Absarokee loam series, and may be classified as a Slope silty <br />clay loam. They contain little salt and are also low in fertility. <br />The areas represented by number 4 are formed from a Mancos shale type of material in place; <br />that is, they are not alluvial. They are relatively shallow and may be classified as a Wetlands <br />silty clay, part of a broader Persayo-Chipeta series of soils. Several of the areas had small <br />amounts of flowing water emanating from between the shale layers and support agrass-wetlands <br />community of vegetation. The water appears to be ephemeral as a result of recent precipitation <br />in the area. Deposits of salt may be found around where the water is flowing out of the soil. <br />This soil was the highest with respect to salt content and also had the highest sodium adsorption <br />ratio (SAR); however, both the salt and the SAR are still acceptable. Due to the very heavy <br />texture of the soil, these areas should be avoided for remediation work. <br />Areas 5 and 6 are from a deep, wide gorge which runs through the north edge of the proposed <br />disturbed area. They are different in that area 5 is from anorth-facing slope of the gorge and <br />6 is from asouth-facing slope. Area 6 samples were acidic in nature, probably due to their <br />exposure to more weathering as they face south. They may be classified as silt loans, part of <br />the Torriorthent soils portion of the area. They are indistinct and may be disregarded in terms <br />of soils for remediation. However, they are a part of the overall area to be disturbed. Also, <br />most of the uppermost reaches of the area are composed of soil represented by number 5, but <br />the slopes are not as severe as those in the gorge. <br />Several gullies extend down from a formerly disturbed area and are filled with coal spoil. They <br />were not examined in terms of quality and should be avoided for any remediation stockpiling. <br />They are noted by the letter "C" on the map. <br />• <br />2 <br />
