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.
