"The Bend Arch and announced in south. The deeper Bend lies in Archer, Clay, Jack, Wise, Parker, Tarrant, and Johnson counties, Texas. To the north it rises again. As to the east there is no information. Granite was drilled into in northern Clay county, and against this granite the Bend arises. Look this up in my Paleogeographic maps. The Bend in all shale under south- southern Edwards, northern Hvalde, central Archer and southern Bandera counties, to the northwest of the San Saba uplift. In southwestern Kimble county the Bend has some limestone, and it is because of this occurrence that the Black Shale of the western counties is correlated with the Bend. This looks like evidence of the Bend fauna coming in across Imora. All of these places are now deep below the Cretaceous. Adder lines some about these deep ores.
