Generally, soils of the area are shallow and coarse-grained being derived from the <br /> underlying sandstones and shales. Bedrock exposures are common and scattered <br /> throughout the area. The valley bottoms are underlain by alluvial and colluvial deposits <br /> which are also coarse-grained, however, are deeper compared to soils of the mountain <br /> slopes. <br /> Vegetation varies from riparian in the valley bottoms to pinyon-juniper, oak brush, <br /> and pine cover on the side slopes. Vegetation cover ranges from 1000/6 in the valley <br /> bottoms to near 0016 on the steeper side slope rock outcrop areas. <br /> 1.2 Sampling Station Descriptions <br /> To fully assess the hydrologic balance of surface and ground water resources in the <br /> area of the two mines, the monthly sampling program which was initiated in February, <br /> 1984 has continued through this reporting period. Additional sampling emphasis was <br /> placed on some of the stations because of increased mine operations on the surface (as <br /> discussed in the Annual Report of 1984). The following are descriptions of the sampling <br /> locations utilized during the quarter. These stations correspond to those shown in <br /> Figure 1- <br /> PRS-1 Located on the Middle Fork of the Purgatoire River above the surface <br /> facilities of the New Elk Mine. This station was selected to assess <br /> stream quality and flow above mining activities. <br /> PRS-2 Located on the Purgatoire River below the New Elk and above the <br /> Golden Eagle surface facilities. This station was selected to assess <br /> stream quality and flow relating to potential effects of the New Elk <br /> Mine and establish baseline data above the Golden Eagle Mine. <br /> PRS-3 Located on the Purgatoire River below the Golden Eagle surface <br /> facilities. This station was established to assess potential effects of <br /> mining on stream quality and flow. <br /> -3- <br />
