Pg. 7 (fig. 3), 24-26, pls. 1, 2. See also 1956 [abs.], Dissert. Abs., v. 16, no. 1, p. 101. Moonlight formation. Proposed for lithologic unit in Orchard Peak area which is equivalent to PACHYDISCUS silt or Ragged Valley shale of Coalinga area and elsewhere. Consists of two facies: a light-colored siltstone facies in Devil's Den and Sawtooth Ridge synclines and a dark-gray clay shale west of Sawtooth syncline; transition between the two facies occurs rather abruptly, near west end of Sawtooth Ridge syncline. Thickness at type locality 1,550 feet; 1.2 miles to the southwest in Sawtooth Ridge syncline, thickness is about 375 feet, this suggests that the Moonlight may be a tongue which pinches out toward south. Except where faulted, formation conformably overlies Serpiente sandstone (new) and underlies Red Man sandstone (new). Contains BACULITES CHICOENSIS, LIOPISTHA, and Foraminifera. Age is Late Cretaceous.
Type locality: Moonlight Valley which runs along south limb of Devil's Den syncline, just north of Avenal Ridge, northeastern Kern Co., southern CA.
