Late Cenozoic beds in the Upper Safford Valley, Graham County, Arizona

A sequence of poorly to medium**well consolidated sediments occur in the upper Safford Valley. They consist of lacustrine de­ posits, herein called the Solomonsville beds, overlain by terrace gravels and alluvium. On the basis of contained fossils the upper Solomonsville beds are post-early Kansan in age. They are equivalent to a part of the Gila conglomerate. The sediments of the Solomonsville beds were derived from a local source area. The faulting which produced the basin in which the Solomonsville beds were deposited was prior to
