unit. However, the top of the Bucatunna Clay Member presents a gen-
erally uniform, easily identifiable surface whose attitude can be com-
puted readily (fig. 11). This surface strikes about N. 65 W. and dips
about 30 feet per mile toward the southwest. The top of the lower lime-
stone of the Floridan aquifer also dips southwestward at 30 feet per
mile and has a strike of N. 60 WV. Probably the sand-and-gravel aquifer
has a gentler dip.
