contorted bedding and locally lime- indurated concretation-like bodies of cross-bedded and/or contorted SS. Above this the unit contains elongate but lenticular thin beds of lignitic, locally shaly sand, some ste dipping or arcuate. Also small OB weather cones scattered throughout and in stringers. From about 22.0 to 30.0 above base are the large, conc.-like concentrations of X bedded SS which weather into huge spheroidal masses 8' in diam. Above these, SS as below with more lignitic lamine in local beds and locally, abundant small Fe cones The SS in this interval is colgate-like, a fairly "dirty" subgraywacke,, may even have some glauconite locally- at least it has some light-green quartz. At top SS is loc. indurated - not by CaCO3. Contact is sharp, loc. irreg.
