The ranking of the individual sites is given in Table 1 above. These sites are considered the highest priorities for reclamation. In addition, there are two draining mine adits where hydrologic controls should be beneficial, and may stop all drainage. Each of these sites will be discussed in detail below. In general, the sites that received a ranking of 1 are near or in a stream channel, and exhibit the greatest amount of historic erosion. Williams, Rio Grande and Crown Point & Virginia (Sites #1 and #2) Location This site is located near the headwaters of the mainstem of Virginia Canyon (Figures 3 and 6). This group of mine waste piles was sampled as sites 1 and 2. Site #1 consists of the waste rock pile 23
