The volcanic island of Saba contains sulfur deposits. In 1887, a mining company opened a mine here on one of the rocky shores. The lack of the anchorage along the island's shoreline made loading of sulfur extremely difficult. Workers were forced to transport sulfur by cable car 100 meters/ 300 feet above the sea to the offshore Green Island. After a year, however, the mine was abandoned.
Saba miners faced the extreme conditions in the underground corridors. The temperature inside is at constant level, 34.4 °C/ 93.6 °F with the relative humidity of 98.4%. We only went inside for a few minutes. The warning sign at the entrance stated that staying in the mine for more than 15 minutes could lead to fatal heart injuries.
