Since 1974, how- <br />ever, the land use has been grazing. Cattle, sheep, or horses graze during all parts of the year. <br />Wildlife populations within the area are restricted due to extensive disturbance from past mining <br />activities, deteriorated condition of vegetation due to overgrazing, and the lack of a reliable water <br />supply. The general area may be within the migratory route of peregrine falcons. A few other <br />species of small mammals and birds may inhabit the site. <br />Structurally, the area is underlain by the Poison Canyon, Raton, and Vermejo Formations, which dip <br />tw.o to five degrees to the west-southwest. Coal that was to have been mined by the operation <br />lies within the Vermejo Formation. A total of five seams exist within the Vermejo. These seams <br />are the Robinson, the Pryor, the Walsen, the Lennox, and the Cameron. These seams lie within a <br />sequence of sedimentary rocks consisting of sandstones, siltstones, shales, and carbonaceous and <br />silty shales. <br />Underlying the Vermejo Formation is the Trinidad Sandstone, which is an aquifer of significant <br />regional extent. However, numerous old mine workings have had a serious affect on groundwater <br />4 <br />
