Formation described in detail. Pond limestone "C" is about 3 ft thick and is composed of somewhat cross-bedded hard bluish-gray, coarsely crystalline fossiliferous limestone. Pond limestone "B" is 0 to 1 ft of very fossiliferous crystalline limestone. Pond limestone "A" ranges in thickness from 1 to 16.5 ft and is composed of massive, slightly reddish-gray oolitic or foraminiferal limestone, everywhere asphaltic.
