Alpine, April 6 - 1936 Tuesday Started at 8.10 for Baptank (300miles to Mara- thon and tren 25.6 to the tank). I tried to collect upon Baptank all the morning and got about 6 speci- mens. Failed to find hidden good localities, see opposite page. Dellards, Baker and Blanchand started E. to make out the structural relations between the Upper Sep- tank and the Lower Baptank. The fossils collected show the normal Lower Baptank fauna of that Cenoman time. I had also seen Lower Baptank and south where they worked but to the east saw no fossils. After lunch we all to the east went at it again and came to the conclusion that there is no break between the Lower and Upper Baptank. As we walked farther east to shore, the Paleyric strata go back into the Cmenachian. The Upper and Lower Baptank strata, a padmed and tucked, and the rocks jumped somewhat or that at this to me another normal the rocks stand nearly at right angles. The folding is therefor disturbed and thrown into a jumble. To me it appeared to be a fault present only on the eastern in the rally between the Up. and Low. Baptank. and more thrust (to be clear) conditions. This star sea in a little valley headed by a great yellow face of Lower Baptank strata. Fault and Thrusts to NNE↑ Cenomanian.
