About This Publication
This map illustrates the geology at the northern margin of Powderhorn Lake and the western margin of Matagorda and Lavaca Bays. The area’s geology consists of sediments deposited within a Pleistocene fluvial–deltaic system and a Holocene bay–estuary system. Map units include Pleistocene muddy and sandy facies of a fluvial–deltaic setting and Holocene bay-margin deposits.
