Summary:

Pg. 48-49 (article by C.E. Wier). †Ditney Formation. Fuller and Ashley (1902, p. 2) applied name to rocks between Somerville Limestone (now West Franklin Limestone Member of Shelburn Formation) and Inglefield Sandstone Member of Patoka Formation. This section included 20 feet of shale, thin sandstone, and thin coal exposed in Ditney Hills, Warrick County (secs. 4, 5, and 6, T. 5 S., R. 9 W.). Wier (in prep.) assigned these rocks to Patoka Formation and retained name Ditney for the coal that was called Ditney Coal by Fuller and Ashley (1902, p. 2).
