Soils are generally shallow and coarse-grained. Derivation <br /> is 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 coarse- <br /> grained and deeper than soils of the mountain slopes. <br /> Vegetation varies from riparian and blue grama complexes in <br /> the 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 <br /> 1984 to assess the affect of mining operations on surface and ground <br /> water quality and quantity. Tables 1 and 2 are a summary of the <br /> current water monitoring program. This program has undergone several <br /> revisions over the last five years. These revisions have resulted from <br /> data review by the Division and WFC. Sampling emphasis has been placed <br /> on some of the stations because of increased mine operations on the <br /> surface (as discussed in the Annual Report of 1984 ) . Following are <br /> descriptions of the current sampling locations. Station locations <br /> are shown on Figure 1 . <br /> PRS-1 Located on the Middle Fork of the Purgatoire River above the <br /> surface facilities of the New Elk Mine. This station was <br /> selected to assess stream quality and flow above mining <br /> activities. <br /> PRS-2 Located on the Purgatoire River below the New Elk and above <br /> the Golden Eagle surface facilities. This station was <br /> selected to assess stream quality and flow relating to <br /> potential effects of the New Elk Mine and establish baseline <br /> data above the Golden Eagle Mine. <br /> -2- <br />
