EXHIBIT D - SOILS INFORI~ON <br />Lease tract JD-6 falls ~~~ithin the zone mapped as unit 3 <br />on the General Soil I4ap - Dolores River Basin. It is <br />• described as "rock outcrops and very shallow soils of <br />the canyons". It is the most extensive mapping unit of <br />the Dolores River Basin, constituting approximately <br />one-third of the area. <br />• <br />A typical landscape is characterized by the deep sandstone <br />canyons with steep slopes (from 25-100q~) and long narrow <br />valleys. The dominant parent material for these soils is <br />sandstone with some shale and alluvium. <br />This mapping unit can be divided into three general components. <br />Rock outcrops account for about 45 percent of the unit. These <br />are largely of sandstone with some small shale outcrops. <br />About half of the unit 0+996) is in shallow (20 inches or less) <br />and stoney soils, generally with a light-colored, loamy surfac <br />layer. Mixed alluvial soils of the Dolores and San I~dguel <br />River bottoms account for about six percent of the mapping uni <br />The followir~ 1966 Great Groups, Subgroups, or land types are <br />found in this mapping unit: <br />PERCEA`T OF <br />APING U1dIT <br />GROUP <br />45 <br />25 <br />20 <br />4 <br />2 <br /> <br />Rock outcrops <br />Haplustolls <br />Torriorthents <br />Lithic Argius~olls <br />Boralfs and Cryobarolls <br />Torrifluvents <br />In most, areas mapped as unit three the mean annual temperature <br />falls between 42 degrees F and 52 degrees F, with a frost free <br />period of between 100 and 160 days. Sheet erosion is describe <br />as moderate. Sediment yield is estimated at less than 0.2 to <br />1.0 acre feet per square mile per year. <br />The dominant land use of mapping unit 3 is for range and wil <br />life. Of the 974,000 acres it covers in the Dolores River <br />Basin, 3,800 acres are in irrigated cropland and there is no <br />dry cropland. <br />The dominant ground cover associated with mapping unit 3 is <br />pinyon-juniper. At higher elevations oakbrush, serviceberry, <br />and grass are more prevalent, while willows and cottonwoods <br />may be found along the narrow valleys. <br />(The preceeding paragraphs describe large categories of the <br />Dolores River Basin, into which the JD-6 property falls.) <br />
