The influence of the northern aspect on the <br />effects of solar radiation, coupled with the relatively high <br />precipitation on the plateau, results in well-developed, deep <br />soils which support a dense vegetative cover. This becomes evident <br />when one compares the soil and vegetative cover which exist on <br />the southern aspect landscapes immediately north of the disposal <br />. site. <br />GRAND VALLEY FACILITIES <br />The Terminal facilities site presents somewhat different ecological <br />constraints to reclamation which can be handled by managing the <br />areas according to the intended post-mining land use of agricul- <br />tural pastureland. Precipitation at this 5500 foot elevation <br />site is less than that experienced at the 8,000 foot levels of <br />the Dow West property and temperatures are commensurately higher. <br />Soils are well developed, but slightly saline due to the alluvial <br />nature and source of the parent material. However, the aspect <br />is rather flat and therefore creates no extreme conditions due <br />to solar radiation. <br />These more arid site conditions are presently overcome by manage- <br />. ment practices which include tillage, fertilization and irrigation. <br />E-16 <br />
