The upper Sulphur Springs geothermal area cuts the SW flank of Morne Plat Pays stratovolcano and lies just inside the large scarp formed by collapse of the edifice. The thermal area consists of steaming, hydrothermally altered ground with yellowish area marking many sulfur-encrusted fumaroles with temperatures of from 90-100 degrees Centigrade measured during the past century. Minor hot springs are also present.
