A distinctive group of lithologies identified by geophysical and drillers' logs in the subsurface in McDowell and Wyoming Cos., WV, is here named the Ravencliff Member of the Hinton Formation. It consists of a heterogeneous sequence of sandstone, quartz pebble conglomerate, and interbedded variegated shale. It is restricted to the strata which conformably overlie the Little Stone Gap Member and conform-ably underlie the radioactive "Hot Shale" marker bed of the Hinton Formation. Thickness varies from 410 to 465 ft. Age is Late Mississippian (Chesterian).
