About This Publication
The Point Comfort quadrangle lies along the northeast margin of Lavaca Bay and includes the Lavaca delta where it progrades into the bay. Similar to the geology of the adjacent Kamey quadrangle, the geology consists of sediments deposited within a Pleistocene fluvial–deltaic system (Beaumont Formation), and Holocene bay–estuary and fluvial–deltaic systems. Holocene geology is dominated by delta-plain deposits of the Lavaca River and Huisache Creek. Other Holocene sediments include alluvium, levee, abandoned levee, bay margin, and bay-margin spit deposits.
