Additional Information: Sulfur production at the Boling Dome is from the crest of the caprock to deep down the southeast flank of the cap. The first well went into production in March 1929, using the Frasch method for removal (pumping steam into the ground to melt the sulfur, then pumping the liquid sulfur out). The sulfur reserve covers more than 1,500 acres. This reserve, owned by Texasgulf, Incorporated, has produced more sulfur than any other sulfur mine in the world. As of 1990, 80.5 million long tons of sulfur had been removed. (ref. Michel Thomas Halbouty, Salt Domes, Gulf Region, United States and Mexico (Houston: Gulf, 1967; 2d ed. 1979)).
