Fig. 2.28.— Topography of the Miami Oolite in SE Florida. The oolite formed during the last interglacial, about 125 ky ago and has
been exposed to weathering in a humid, tropical climate (about 160 cm annual rainfall) ever since. Intensive karst weathering has
produced isolated sinkholes and probably lowered the surface, but the depositional morphology of the formation still shows the pattern
of sand bars and intervening channels in the northwestern part of the formation and a narrow longitudinal shoal in the southeast. The
latter formed during a lower sea-level stand near the end of the interglacial. Compilation based on Halley and Evans (1983) and contour
map by US Geological Survey.
