p,~~la,;;,l Correspondence Only <br />w~~ <br />., <br /> <br />T0: Rey 'faliafcrro <br />FROM: Don Bogart ~~ <br />DATE: January 6, ]977 <br />.lanuary 6, 1977, I visited the Andesite Rock Company mine above Lyons. <br />Tlris mine has been operating for several years. The lease that they are <br />operating on consists of H2O acres; however, probably an area of 80 to <br />IliO acres is all that will ever be mined. The estimated life of the mine <br />is projected to he for twenty more years. It is located on the Srnirh <br />St. Vrain River; however, there is no encroachment on the river itself <br />and since the rock is all mined in a dry state, there are no problems <br />with effluents or other drainage wastes to contaminate the stream. <br />fbe operation consists of blasting from the face of an almost perpendicular <br />hluff, then hauling it to the railroad in Lyons or by truck to various <br />sites. <br />The steep slopes have scattered cover of mountain mahogany and skunkbush <br />and an occasional clump of grass. Some deer are known to inhabit the <br />are;,; but the slope is extremely steep and generally northerly slope, so <br />. not tuo much use is made of the browse species by deer. Otherwise tiierc <br />is insignificant use of wildlife. <br />What little topsoil there is had been stockpiled and will be replarcd at <br />the end of the operation and reseeded to SCS specifications. <br />'there are no known threatened or endangered species in the area. <br />DB:cp <br />•~ <br /> <br />STATE OF COLORADO <br />DIVISION OF WILDLIFE <br />DEPARTMENT OF NATURAL RESOURCES <br /> <br />
