Summary:
Pg. 44-45, pl. 2. Woodpecker limestone member, 2nd from uppermost member of Nevada formation. Consists of thin- to medium-bedded limestone not uncommonly sandy or argillaceous. Limestones fine-grained to aphanitic or porcellaneous and light-olive-gray to dark-gray. Weathering of shaly partings produces pinkish or yellowish colors. In Oxyoke Canyon, includes a somewhat "punky" calcareous shale carrying numerous pteropods of Styliolina affinity. Thickness ranges from 220 to 450 feet. Lower boundary notably gradational with underlying Sentinel Mountain dolomite member (new) whereas contact with overlying Bay State dolomite member (new) is quite sharp being marked by varying thickness of light-gray dolomite sand at base of Bay State dolomite member. Calcareous nature of unit between the two dolomite members serves to distinguish it. Age is Middle Devonian.
Type locality: in gulch draining south slope of Woodpeckers Peak, which is situated on north boundary of Oxyoke Canyon, in vicinity of Eureka. Origin of name not stated, but probably named from Woodpeckers Peak [Lat. 39 deg. 27 min. 00 sec. N., Long. 115 deg. 53 min. 44 sec. W., Pinto Summit 15-min quadrangle, White Pine Co., NV].
