[D6086] -> Etcheminian. The upper so far have gone of red shale and coarse red sandstone. Usually the red shales are very thin but at the top a layer goes to 5 feet thick. Also micaceous. Much of the material came from the trachyte and the red color seems due to oxidation. This Etcheminian maybe Lower Cambrian and may also be Parterqure. Hard to say which. For base see legend.
