<br />-3- <br />SITE CONDITIONS <br />The site 15 failow agricultural iand located approximately <br />2 miles southeast of Hayden, Colorado as shown on Fig. 1. The ground <br />surface slopes downward to the southeast with a relatively uniform <br />elevation differential of approximately 20 feet across the proposed <br />construction area. The truck dump, crusher and stockpile are Tocated <br />downslope from one another with the train loadout located across a minor <br />draw to the northeast. Abroad ridge north of the site will be cut by <br />the haul road and railroad spur alignments. The Dry Creek drainage <br />system, located to the south and west, will be crossed by the railroad <br />spur. <br />Vegetative cover consists of light wheat stubble and weeds. <br />• Considerable surficlal cracking, apparently the result of shrinkage, was <br />noted at most Cast hole locations. The ground surface is relatively <br />firm with a light gravel cover and should not impede mobilization of ~ ;{ <br />construction equipment unless it were to become wet. <br />7 <br />i <br />e <br />GEOLOGIC SETTING <br />. s <br />The Hayden Gulch coal handling facility is situated on a strongly <br />sloping (12$) south facing terrace escarpment. The escarpment con~fects <br />the nearly level valley floor of Stokes Gulch and Dry Creek with a <br />nearly level terrace surface located in the northwestern portion of the <br />site. A thin clayey gravel deposit from 2 to 3 feet thick was encoun- <br />tered in Exploratory Holes 20 and 21 located on the terrace surface. 3 <br />• <br />;:~ <br />a <br />:A <br />. -. :V' <br />
