... the Ordovician Ledbetter slate. The brachiopods, Nisusia sp. and Acrotreta sp., were found near the middle of the formation on Gladstone Mountain. They indicate, according to Bridge, an early Middle Cambrian age, as do the trilobites found at a lower horizon in the Metaline quadrangle. The upper third...
