Paleozoic and Tertiary rocks cover and igneous intrusions in places obscure observations, while the examination underground was very incomplete.The Black Hills are an oval-shaped mountainous tract, trending nearly north, on the extreme western edge of South Dakota. Physiographically this mountainous tract is the dissected core of an oval-shaped domical uplift which involves rocks as late in age as Tertiary.Erosion has stripped the cover from this oval dome and etched the underlying basement series of pre-Cambrian schists.It is with this . . .
