Lawrence? The base is my notion being a zone 104th circulation against the inference Sturton Rim shales, 18" thick. First 6 feet of 1.6 inches, then a kettle bed with the stones ranging from 1 to 4 inches. Then 6 feet also with large kettles and more a len notion. Then 80 feet more with zone and shale of these large pebbles and many black flinty pebbles. For about 65 feet of lighter colored beds with dark zone but distinct conglomerate of any kind. Then 40 feet with smaller and larger pebbles. No shale up to this point, all heavily bedded sorts of conglomerate and sandstones. Now the series goes thence bedded and has very thin shale zones but the pebbles for that half, the size runs to top about 350 feet. Set order in upper part, This gives a thickness of 540 feet and if anything my estimates are under the small. The Penn. Lurry has 460'. The Penn. Lurry makes two zones: 1 Oreida Oreida Conglomerate sandstone 290 feet * lower conglomerate 170 460 To me this is all one series. Looked carefully in Anthrophyces, but found none. It's Lawrence, unmistakably = Lawrence unit.
