"Richwood: A couple of fragments of such a large specimen were collected by the species in general smaller, but layers quite rapidly. The Rhynchonellae are especially common near the seam of laked shale at the top, with curvata and a few Dalmanellas. Below the shales of 5.3.8 ft. And grading up to the latter lies an irregular mass of tuff-breccia which varies in thickness from 12 feet to about 3 feet in the space of about 30 yards. The nature consists of a Christywood lithologically similar to the black clay mud of the shales at measure and imbedded. In these are scattered small pebbles, generally angular fragments weathered into cream state, of rhyolite, and occasionally larger fragments as much as 1 inches to 5 inches thick of dark rhyolite glass. There are also fragments with a thin crust of the gray, but white or buff colored rhyolite similar to that of north Lick, and also large concretions 5 or 6 inches thick. Usually there were not found occasionally pieces of black shale, few inches thick containing Dalmanella, Actinoptera similar to the surrounding immediately underlying shales. In fossils are found on the tuff proper, but in the overlying shales 5.3.8 ft. Fossils occur in the patches of shale which contain ash fragments, locally as well as in the pure shales. The tuff is very variable from joint to joint. A band of grey -new 133 has very few ash-pockets or cinders and looks almost like blue shale. Below the massive tuff-breccia 1/33 there follow 14 feet of thin black shales, somewhat laked and alternating with glassy rhyolitic flags and a couple of 2 inch conglomerate breccias, the latter commoner near the top. The rhyolitic flags are 1" to 1 1/4 thick and two inches or eight inches thicker. This thicker flag displays the interesting phenomenon of being under (or gummery) at the bottom for an inch and a half and then grading upward into the typical dark grey glassy rhyolitic rock, which is not generally frother hardened and somewhat freemally due to the volcanic activity in the neighborhood. There 14 feet strike N. 35 W., and dip N. 55 SE at an angle of 41°. They are 5.3.8 L (J.) and contain: Dalmanella abund throughout Rhynchonella* occasional abundant remains Chonetes denysi rare.
