Dimple formation, 925' Dimple hills to G.E. / Marathon. Too far away to go there. (1) Li., Haed chert, Haell sh. 46 Li. have a few marine fossils. (2) Can be seen along O. R. R. R. between Drammond and Heymond (935 feet). 105-106. Also to be seen 1/8 mile S. of Marathon (700S. 15 E.). Has some Perm. fossils. Also W. of Heymond, 1/4 mile. Here fossils appear to be varied and common. Heymond formation, 500' (2) H. and K. Lime Tresses. 107. Can be seen E. of Heymond along R.R. Day, may be tresses overthrust up on Dimple. And Dimple forms to the like tresses. Baker then has a time of Oxt. erating (107-111). Folding and overthrusting from S.E. to N.W. Does not appear to be certain of his facts (108). Was there folding at all at the time? Is the structure post Permian? Post-Tertiary with diorite and neathalence = Permian times. around 2000' Baptank formation, over 1000' Troutt tr. = Cicer. (1) Position in column not certain known. Cmpl. at these, alt., mitt le., N. & S. sh. Rich m fossils @ p.38 47 Middle sh., mitt le. Upper marly le. Baptank is 24 miles N.E. of Marathon; extends 15 miles S.W. (2) Lower Baptank rich in fossils. Seen 3 miles S. of Baptank (38). Also 4 miles W. of Marathon, most m. of R.R. See list of forms p. 38-39. Have Bakistoceras smithi and Tegalifera. Upper Baptank seen in sections 7, 8, 9. = 520 feet, Correlated with Elmdale of Kansas. See list of fossils p.40. Helden does not know if there is an unconformity below (46) with Heymond. Baker and Boese saw an unconformity between Lower Baptank and Heymond. Look for angular unconformity at the Baptank, and beneath Wolfcamp.
