PG. 149 Brooks Ranch Collection 8/28/58/3 - S. crassitectoria zone above section 10. Collection 8/28/58/4 - Trit. zone at top of section 11, bed 19-20. This limestone seems to be a remnant and is cut out west and east ward except at a couple of places on Brooks Ranch. The upper beds of Sec. 11 from about bed 12 on up to 22 seem to be higher than the major portion of the ledge forming limestone 6-12. Another patch of this higher limestone is found behind the Brooks Ranch house.

The Sec. 11 is apparently a hill with conglomerate around the sides.
