Soils are generally shallow and coarse-grained. Derivation is <br /> from the underlying sandstones and shales. Bedrock exposures are <br /> common and scattered throughout the area. The valley bottoms are <br /> characterized by alluvial and colluvial deposits which are also <br /> coarse-grained and deeper than soils of the mountain slopes. <br /> Vegetation varies from riparian and blue grama complexes in the <br /> valley bottoms to pinyon-juniper, oak brush, and pine cover on the <br /> side slopes. Vegetation cover ranges from 100% in the valley bottoms <br /> to near 0% on the steeper side slope rock outcrop areas. <br /> 1.2 Sampling Station Descriptions <br /> A monthly sampling program has been conducted since February 1984 <br /> to assess the affect of mining operations on surface and ground water <br /> quality and quantity. Tables 1 and 2 are a summary of the current <br /> water monitoring program. This program has undergone several <br /> revisions over the last six years. These revisions have resulted from <br /> data review by the Division and WFC. Sampling emphasis has been <br /> placed on some of the stations because of increased mine operations <br /> on the surface (as discussed in the Annual Report of 1984) . Following <br /> are descriptions of the current sampling locations. Station <br /> locations are shown on Figure 1. <br /> PRS-1 Located on the Middle Fork of the Purgatoire River above <br /> the surface facilities of the New Elk Mine. This station <br /> was selected to assess stream quality and flow above <br /> mining activities. <br /> PRS-2 Located on the Purgatoire River below the New Elk and <br /> above the Golden Eagle surface facilities. This station <br /> was selected to assess stream quality and flow relating <br /> to potential effects of the New Elk Mine and establish <br /> baseline data above the Golden Eagle Mine. <br /> -2- <br />
