At this place Little river cuts close toits left bank and leaves exposed a bluff of limestone and chalkabout 130 feet high. The chalk proper forms the uppermostbed in the section, and is here about 30 feet thick, with amaximum of 40 feet. In 11 south, 29 west, Section 35, northeast quarter of thenortheast quarter, is the section shown in Fig. 4. The lower 100 feet contains a good many fossil oysters, and Fig. Section of Bluff at White Cliffs. is not so pure as the 30 feet overlying it. In places the bedimmediately beneath the chalk is sandy; this is showm at thebase of the cliff at Ivinsworthys old lime-pit, a short distancenorth of the cliffs. Dr. K F. Drake, who lately visited WhiteCliffs, records the following section of the beds beginning atthe top of the cliff: (1) 20 feet massive white chalk. This bed is probably 30feet to 40 feet thick, but only 15 feet to 20 feet is is the bed to be used for cement, etc. (2) 10 feet of almost white pure chalk, with three bands ofmore arenaceous rock. (3) 25 feet of rock, harder, whiter and less arenaceous thanNo. 4. THE CEMENT-MATERIALS OF SOUTHWEST ARKANSAS. 51 (4) 10 feet of rock, harder, whiter and less arenaceous than No. 5.
