A salt deposit located 8.9 km (5.6 miles) ENE of Matagorda along the Intercoastal Waterway Canal, on private land. Discovered in 1902 by W. Cash and W.T. Goode. Operated by the Texas Gulf Sulfur Company. First production was in 1919 and the last was 1970. Production periods included 1919 to 1932, 1936, 1965 to 1970. MRDS database accuracy for this location is not stated. Dome, H2S, and sulfur were discovered during an oil test in 1902.

Mineralization is a salt dome deposit (Mineral occurrence model information: Model code: 255; USGS model code: 35a.7 (35ag); Deposit model name: Salt-dome sulfur), hosted in the Middle Jurassic Louann Limestone and the Late Jurassic Louann Salt. The ore body is 18.29 (??) meters thick with a depth-to-bottom of 365.76 meters and a depth-to-top of 274.32 meters. The depth to caprock is 825 feet, to the S it is 900 feet, and to the salt it is 1,100 feet. The volume of salt was calculated at 0.7 cubic mile to 10,000 feet of depth. The ore body is 300 acres in aerial extent. Local alteration included biogenic alteration of anhydrock to limestone. Local rocks include rocks of the Beaumont Formation, areas predominantly sand.

Local geologic structures include a piercement salt dome.

Workings included the wells and surface infrastructure necessary for the Frasch production of sulfur. The mill had a capacity of 1,500 tons per day of S.

Production data are found in: Halbouty, Michel T. (1979).
