Mineral-water pool at the Berkeley Springs Resort in Berkeley Springs, West Virginia. (While the area was part of Virginia prior to 1861, the town was incorporated as Bath.) The area contains mineral water springs that were frequented by Amerinds, possibly for thousands of years. After European settlement, the mineral springs drew many visitors from urban areas. Notable colonial visitors to the area included George Washington and James Rumsey. Berkeley Springs remained a popular resort area during the early years of the United States. The area continues to be a popular resort area, with tourism as the main industry in the county and four full-service spas that use the mineral water. Photo by Carol Highsmith.
