This 1:1,000,000 scale map shows salt dome locations and salt bed structure in onshore Texas. The GeMS GIS database contains structure contours for both domes and bedded salt.  Source data include structure contour maps between scales of 1:2,000 and 1:24,000 published between 1925 and 2021.

On Sunday, April 2, 2023, a sinkhole formed on the northwestern flank of the Hull salt dome in the city of Daisetta, Texas (fig 1).

The hydromechanical properties of the uppermost basement and of the basement–sediment interface influence multiple geologic processes of societal relevance, including the flow of groundwater; the accumulation of hydrocarbons, economic minerals, and geothermal resources; and the response of seismo
