The Saratoga Springs are located approximately 25 miles (40 km) north of Albany, New York and just south of the Adirondack Park. Approximately 18 springs and hot well discharge 55°F (13°C) carbonated mineral water along the Saratoga fault between Whitehall and Albany, a distance of 65 miles (105 km). Most of the mineral waters have been obtained by drilling wells, the sites selected where bubbles of carbon dioxide issue from the ground. The springs have been used for drinking and bathing in spas where it has been considered a cure for everything from skin disorders to digestive problems, and the water and carbon dioxide bottled and sold as a commercial product. It has been used by the Indians, developed as a resort spa, and now designated as Saratoga Spa State Park. Some geothermal activities are still accessible for public viewing, including the only spouting geyser east of the Mississippi River
