Summary:
Pg. 14. Bostwick member of Dornick Hills formation. The most resistant part of Dornick Hills formation is a massive limestone conglomerate with associated limestones and sandstones known as Bostwick member. It disappears northward from Ardmore. Above Bostwick member occur 3 or more very fossiliferous limestones including the coarsely crystalline and oolitic Lester limestone. The Bostwick member lies higher in [the] formation than Otterville limestone.

Summary:
Pg. 30-32. Bostwick member of Dornick Hills formation. Forms Bostwick Ridge. Lies 750 feet above Otterville member as here defined, and 400 to 500 feet below Lester limestone member to north of Ardmore, and 800 to 1,000 feet below to south. Included in this interval are 2 or 3 other highly fossiliferous limestones from a few inches to 2 feet thick. Maximum thickness of Bostwick member 300 feet. It disappears within a mile along the strike in each direction from Dornick Hills Country Club, due either to strike faulting or to unconformity within Dornick Hills formation or to a combination of these 2 factors. Has not been yet identified certainly anywhere north of that locality.
Type locality: on Bostwick Dairy Farm, in W/2 NE/4 sec. 11, T. 5 S., R. 1, E., whose buildings stand upon the ridge, Carter Co., south-central OK. Probably named from Bostwick Ridge or Bostwick Dairy Farm in Carter Co., OK.
