profitable despite the claims of being the most productive in the area. The <br />meters -thick target gravel caps most of the local high points and has broad <br />exposure in the miles -wide dissection of Timberlake Creek and along its <br />tributaries. (Conner et al. 2007) <br />The 2007 recording was fairly cursory due to the fact that no artifacts were noted <br />within the inventory area for the previous project, and the size of the area mined is over 80. <br />acres. The present inventory mapped and photographed the north end of the site, an area <br />measuring approximately 1300 feet N -S by 1200 feet E -W (at the widest point). Noted with <br />this recording are two large dump concentrations at the west perimeter of the site. The dump <br />concentration farthest to the north measures roughly 150 feet by 90 feet. The second <br />concentration is adjacent and southeast of the first and measures approximately 130 feet in <br />diameter. Both of these have been excavated to roughly two feet deep in areas and <br />contain metal machinery fragments, gas cans, purple and cobalt glass fragments, tin <br />food/beverage cans, wire, ceramic fragments, a piece of a shoe, a metal funnel, and a 0.5" <br />diameter white shell button with two holes. Estimated number of cans is roughly around 100 <br />although many are flattened and fragmented, and an exact count was not determined. <br />Ten items mapped, dispersed throughout the site, contain miscellaneous metal <br />remnants such as pipe, tin sheets, lug nuts, barrel parts, wire cable, stove pipe and paint cans. <br />At the northeast corner of the site is a concentration of roughly 50 threaded wood pins that <br />are remnants from an electrical line (possibly power or telegraph). These pins were used to <br />hold glass insulators that were positioned on a tapered wooden pin, vertically extending <br />upward from the pole's cross arm (commonly only two insulators to a pole and maybe one on <br />top of the pole itself). Numerous photos documenting a sampling of these items were taken <br />and will be submitted with the site form. <br />In terms of datable items noted, hole -in -top milk cans, cans with crimped seams and <br />sardine tins were noted. Dates for the types present can range from 1914 to 1948 (Simonis <br />2001). The presence of the purple glass fragments indicates a date of 1917 or earlier. <br />Manganese was used in bottle glass up to about 1917 in order to give the glass a clearer <br />effect. After this date, ultra- violet rays of the sun would not turn the glass "purple ", a change <br />caused by the manganese content of the glass. Cobalt glass has a wide date range, ca. 1890 to <br />1960. This glass was used for medicines, cosmetics and specialty uses. The shell button <br />noted is difficult to date because of the long history of shell use as a button material. <br />The 1906 BLM- General Land Office (GLO) survey map reviewed during the files <br />search indicated that a wagon road crossed through the north - central portion of the site at its <br />east edge. Coincidently, a two -track road is presently in that area, but it could not be <br />definitively determined to be the original wagon road. The present road is slightly north of <br />the 1906 mapped road and deviates some in its direction. Since the entire site area was <br />apparently dredge mined any remnant of the old road within the site boundary is not extant. <br />15 <br />
