about 40-50' of PowWow Conglomerate and transition zones. It is similar to the basal conglomerate of the Wolfcamp and contains siltstones and sandstone possible of the equivalent to the Uddenites zone, but not the same facies. In James Underwood's area the Hueco is about 600-700' in the eastern locality (7/25/57/1) and perhaps thicker in the NE locality (7/25/57/2 & 7/25/57/3). These last 2 localities are near the base of the base of the unit but the exact horizon was not determined. There is some structure complications in this area and so more detailed work is needed. The presence of siltstones, shales and sandstones in the first locality suggest the lower 1/3 and upper 1/3 are not normal deep basin deposits like the middle 1/3 but (continued on pg. 139) PG. 139 7/26/57 Collection 7/26/57/1 from base unit of Igneous rock - above Boquillas limestone (K) - This is a possible freshwater limestone in prevolcanic time.

I've promised Jim to let him know what fusulines are from the second and third localities. In general a measured section in this larger region seems to promise little in the way of fusulines.

Research Lab, Houston, Tex. mentioned many of the oil company fellow find the Hess in the western (Lenox) part is equivalent in age to the Wolfcamp in the type area and eastward. Also
