Pg. 744. Kincaid formation, lower formation of Midway group. Probably 100+/- feet thick in Frio River section. Includes beds 7 to 5 of Vaughan's section of "Myrick formation" on Frio River, about 0.25 miles above Myrick's lower apiary (now Bob Evans apiary), as given in USGS Uvalde folio, No. 64, 1900. The Kincaid formation in that section consists of (descending): (7) rather soft yellowish sandstone, 22 feet 6 inches; (6) soft yellow sandy clay with bluish streaks, some pebbles in lower part, 2 feet 6 inches; (5) nodules of glauconitic sandstone containing considerable number of small pebbles, 6 inches. Underlies Wills Point formation [restricted] and unconformably overlies Escondido formation (Upper Cretaceous). Age is early Eocene.
Type exposures are on old Kincaid Ranch (Lewis Ranch) 0.75 mi above Bob Evans' apiary to 0.25 mi below it, [approx. Lat. 29 deg. 16 min. 44 sec. N., Long. 99 deg. 56 min. 06 sec. W., Chalk Bluff 7.5-min quadrangle, Uvalde Co.], eastern TX. [Lat./Long. coords. from USGS GNIS database and ACME Mapper 2.0, accessed August 19, 2009.]
