Pg. 287. Deep Creek beds. Still farther east [of Fort Ellis] along Deep Creek, exist remarkable lake deposits of both "Miocene" and "Pliocene" age, which represent TICHOLEPTUS beds of Cope. [Same as Deep River beds, the stream having been called by both names and also called Smith River.]

Term preoccupied by an abandoned term of same name used by Emmons, but continued use as a Tertiary formation thought not to be confusing. Thought to be a synonym for Smith beds and Smith River beds. Shown on correlation chart as a Miocene unit of Barstovian or Sarmatian age, younger than Fort Logan formation and older than the Flaxville gravel. Used in Meagher Co, MT in the Montana folded belt province.
