Previously,the land was used for sheep and <br /> cattle grazing. In the late 1800s the small town of Carnegie existed south of what is now Corral <br /> Hollow Road. This town developed around coal mining and a brick manufacturing plant.The <br /> brick plant utilized the ample supply of rich clay found in this area. The town and the brick plant <br /> were abandoned in 1912. The plant was destroyed and the area returned to its natural state in <br /> 1916. <br /> Currently,natural resource use aroand Site 300 is limited to sheep and cattle grazing.The <br /> groundwater supply in the vicinity of Site 300 is not sufficient to support commercial agriculture <br /> irrigation (LLNL 1994). <br /> 10 <br />
