4 <br />• railroad and road construction and deb ris 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 />Mi •r~ Waste Disposal Area <br />The mining waste disposal area is located in a sand hill area approximately <br />4.25 miles (6.61, kilometers) due east of Hotclvciss, Colorado at an elevation of <br />approximately 5700 feet (1737.36 meters). The area consists oS a depression <br />surrounded on the northrre•:L, north, northeast and southeast ly low, rounded <br />ridges. Vegetation is confined to sagebrush (Artemisia spp.) 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 arScose conglomerates, calcite, <br />sandstones and shales. The area is drained by a network of unnamed, west-floVring, <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 0.1+0 kilometers). <br />The closest permanent sources of water are Cottonwood and 1!cDonald Creeks, ap- <br />proximately 1.75 and 2.20 miles southwest, (2.82 and 3.54 kilometers), respective- <br />ly. Faunal resources noted or inferred were rabbits and mule deer. <br />Inventory ldethodoloRy <br />The objective of this investigation was to locate all cultural resources <br />eligible for nomination to the National 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 tans discovered, one hundred percent ground <br />coverage by pedestrian survey was accomplished by survey personnel walking paral- <br />lel five meter corridors (approximately sixteen feet) throughout all pro3ect <br />areas except the Hawk's Nest Mine vicinity. The surroundings of the Hawk's Plest <br />Mine were given cursory examination by walking one tra~sect through the area. <br />• Since the mine surroundings have been excavate3 and leve]1ed and are constantly <br />
