Ciser, Tuesday, March 18-19 19, A fine night and morning. Left started for the south at 6.30 A.M. About 5 miles south of Ciser I collected a piece of the so-called Comanchian conglomerate. Don't its being Comanchian. It looks more like Lofusette material. Then in the northeaster corner Gran Cr. we come upon others of Comanchian. Belms are clear washed white sandstone and those grade up into chalky li. replete with Sythaca and other forms. I have four schinoids for here, a Cideroid collected by Bean, me Enallaster rock by Schneider and Bryne. The other species also by Bryne. This is my first experience in Comanchian rocks. Had lunch at noon at Otag. I've collected in the Comphyllium li.=Caddoli, at the top of the Canno series, also small stream work 1/2 5 miles south of They and then 5 miles to the east. Above this li., there is a chalky series followed by the basal sandstone of the Ciser series. See the forms. De Lindan crude is near here. There is also some local anticlinal structure clay with synduct structure in the middle which is faulty, a normal fault. Be then went to another more more drilling about 2 miles
