A salt deposit located 2.8 km (1.7 miles) NNW of the city of West Columbia, on private land. Discovered in 1901. MRDS database stated accuracy for this location is . Oil and gas production from 1904 to present from flanking and supra-dome reservoirs.
Mineralization is a salt dome (Mineral occurrence model information: Model code: 252; USGS model code: 35a.4 (35ad); Deposit model name: Salt domes: diapiric salt structures), hosted in the Late Jurassic Louann Salt. The ore body is a diapir with a depth-to-top of 198.12 meters. The dome was indicated at surface by a slight topographic mound, central, swampy basin, gas seeps, oil showings and paraffin-dirt beds. Caprock is up to 150 feet thick. The depth to the caprock is 650 feet and to the salt it is 768 feet. Local rocks include the Beaumont Formation, areas predominantly sand.

Pleistocene 0.0117 - 2.588 Ma ID: 3011199 | Beaumont Formation, areas predominantly sand Age: Pleistocene (0.0117 - 2.588 Ma) Stratigraphic Name: Beaumont Formation Comments: (from Moore and Wermund, 1993a, 1993b) Yellowish- to brownish-gray, locally reddish orange, v. fine to fine quartz sand, silt, and minor fine gravel, intermixed and interbedded. Includes stream channel, point-bar, cravasse-splay, and natural levee ridge deposits, and clayey fill in abandoned channels. Forms poorly defined meander-belt ridges and pimple mounds aligned approx. normal to coast and 1-2 m higher than surround interdistributary silt and clay. Channel fill is dk-brn to brnish-dark-gray, laminated clay and silt, organic -rich. Includes marine delta-front sand, lagoonal clay, and near-shore marine sand beneath and landward of bays along the coast. Interfingers with the interdistributary facies of Beuamont Fm. and rests disconformably on Lissie Fm. Thickness 3-10 m on outcrop; thickens in southeastward in subsurface to more than 100 m.
