This was one of the largest sulphur production sites in the world, and was operated by the Texasgulf company, which still has facilities on site, no longer in use, including part of the industrial plant, and two large brick smokestacks. Hundreds of employees lived in the adjacent company town of Newgulf, which only has a few houses that are still occupied now. 8,000 sulphur wells and 12,000 gas wells have been drilled here. Part of the dome has subsided into a lake, and a number of sinkholes have formed, one swallowing a road in 1983. The north end of the dome has been developed into the Wilson Gas Storage Facility, with a capacity of 7.5 million barrels in three storage cavities in the dome, one of which is used for ethane.
