Sunday En Route, Tuxco, Jan 4, 1935. Set out at 7:30, and are in the desert in the Comanchean formations. Go it for all along until 2.55 P.M., when are in the Marathon region. What an enormous mass of telegrams matter was deposited in Cret.Times herein Tuxco and Mexico. When did it all come from. Were there in some sense then in the sphere of the Paleocene of the Miss. Valley. Marathon State Bank, at Marathon, State National Bank at Alpine, or Holland Hotel. If I get going home on my way back had better try one of these places for an auto. The structure of the Texas and older forma- tions again looks to me like folding at the close of Texas time = about Middle Pennsylvania. The older Penn. is fairly well exposed on east side of Haymond. Chances for finds not good, but some should be present. Been driving all afternoon. I return at 8:30 P.M.
