Narration

Geology

Most of the rock layers consist of medium to fine-grained sandstone, but layers and lenses of siltstone, claystone, conglomerate and coal are present throughout the series. Into these sediments many irregular sills and dikes of diorite, andesite and felsite have been intruded. The color of the rocks range from light gray to black, most layers are reddish to yellowish brown.
