Sublake geologic structure from high-resolution seismic-reflection data from four sinkhole lakes in the Lake Wales Ridge, central Florida

Abstract

Seismic-reflection profiles from Lake Wales, Blue Lake, Lake Letta, and Lake Apthorp located along the Lake Wales Ridge in central Florida provide local detail within the regional hydrogeologic framework as described by litho-and hydrostratigraphic cross sections. Lakes located within the mantled karst region have long been considered to be sinkhole lakes, originating from subsidence activity. High-resolution seismic-reflection data confirm the origin for these four lakes.
