Patoot (cont.)
is disclosed in this narrow. The beds are flattened again near the upper party narrow - apparently level. Some irregular basal flows seem to have occurred. Partings only the series in their natural colors occur between those in which the beds are clouded. The occurrence of dikes in this region gives reasons for supposition that shales are actually turned. There is also evidence by leached (now white) brittle and baked conditions of the dark carbonaceous shales in places. For example, in the narrow between red beds and grey camps, the beds freshly exposed are red and white, on the further side, although in normal hundred feet below the grain basal flows they are unaltered, black and grey series. Chemical means should be made. My own opinion is that shales are actually turned, i.e., the carbonaceous matter, locally, resulting from dikelets. They probably were ignited from the dikes, but the combustion appears to be extensive though local and in some instances quite distant from either dikes or skuts.
Some fossil plants collected in red and white shale at 720 A.P. east of camp, i.e., apparently in most eastern red slopes of Patoot.
