recorded and evaluated for determining eligibility for nomination to the National Register of <br />Historic Places (NRHP) as they are encountered according to standards set by the BLM and <br />the State Historic Preservation Office (SHPO). <br />Data collection was conducted by the mapping of observed artifacts, artifact <br />concentrations, and features using a Trimble Geo XT unit (sub -meter accuracy) in <br />conjunction with USGS quadrangle maps that incorporated a 1000m grid. Field notes were <br />taken, including descriptions of the cultural manifestations, vegetation, and soils. Field notes <br />and photo negatives are on file at Grand River Institute, while the photographs have been <br />submitted to the BLM -LSFO. No artifacts were collected. <br />Results <br />There were no significant limitations to the inventory. As a result of the intensive <br />inventory, one site (5MF6447) was revisited and reevaluated. No other resources were newly <br />identified. Site 5MF6447 is described below and location data (available in the BLM and <br />OAHP copies only) is provided in Appendix A on Figure A -1, a 7.5' quadrangle map that <br />shows the resources in relation to the proposed project. Additional detailed information is <br />provided in the attached OAHP Resource Form, also in Appendix A. <br />Site Description <br />Site 5MF6447 was originally identified on the USGS maps as a placer mine and <br />subsequently recorded by Grand River Institute in 2007 in conjunction with a cultural <br />resources project for an access road located at the south end of the site. At that time, the site <br />was described as follows: <br />It is located in an area about half a mile long and a quarter mile wide <br />straddling an interfluvial rise between East and West Timberlake Creeks. The <br />mine appears to be part of the Four Mile or Timberlake Mining District, <br />whose deposits were purportedly the most productive in the vicinity. The <br />Gold Leaf Placer, patented by Mamie Clasbey on March 31, 1916, borders the <br />disturbed area to the north and east, but no record was found concerning the <br />land involved. <br />The area has regular troughs and ridges where gravel was excavated, <br />ostensibly washed, then left as tailings; the effort was systematic to say the <br />least. Irrigation ditches on the flank of Timberlake Creek suggest some water <br />was available for the process. The target deposit is Paleocene gravel derived <br />from the Park Range to the east and consists largely of igneous and <br />metamorphic rocks, including monzonites, and varies from fine to coarse <br />crystalline rock, including pegmatite relicts. The endeavor was apparently not <br />14 <br />
