4 <br />• <br />railroad and road construction and debris contribute to this disturbance. <br />Ground surface visibility ranges from fifty percent in relatively undisturbed, <br />vegetated areas to one hundred percent in locations with heavy vehicular traffic <br />or recent construction. <br />Native lithic materials include sandstone and a variety of river cobbles. <br />Mini 4laste Disposal Area <br />The mining waste disposal area is located in a sand hill area approximately <br />4.25 miles (6.84 kilometers) due east of Hotch<iss, Colorado at an elevation o£ <br />approximately 5700 feet (1737.36 meters). The area consists of a depression <br />surrounded on the northwe L, north, northeast and southeast ty low, rounded <br />ridges. Vegetation is confined to sagebrush (Ante^.isia sow.} allowing autumn <br />ground surface visibility in excess of eighty percent. (Lack of grasses may <br />be due to overgrazing by sheep; see "Inventory Results".) The soil is extreme- <br />ly sandy, and native lithic materials noted include arkose conglomerates, calcite, <br />sarrlstones and shales. The area is drained by a network of unnamed, west-flouring, <br />intermittent tributaries of Cottonwood Creek. The nearest source of seasonally <br />available water is the intermittent tributary network which surround the project <br />area on all sides at a distance of'0.1 to 0.25 miles (0.16 to 0.4.0 kilometers). <br />The closest permanent sources of water are Cottonwood and P`.cDonald Creeks, ap- <br />proximately 1.75 and 2.20 miles southo-rest, (2.82 and 3.54 kilometers), respective- <br />ly. Faunal resources noted or inferred were rabbits and mule deer. <br />Im•entory ?•fethodoloRy <br />The objective of this investigation was to locate all cultural resources <br />eligible for nomination to the IJational Register of Historic Places that occur <br />within project areas slated to undergo surface disturbance. To insure that all <br />cultural evidence within project areas eras discovered, one hundred percent ground <br />coverage by pedestrian survey was accomplis`:ed by surrey personnel walking paral- <br />lel five meter corridors (approximately sixteen feet) throughout all project <br />• areas except the Hawk's (lest Mine vicinity. The surroundings of the Hawk's hest <br />Mine were given cursory examination by walkir~ one tra7sect through the area. <br />Since the mine surroundings have been excavated arxi levelled and are const,.ntly <br />
