Hot Springs, AR
Hot Springs is the 10th most populous city in the U.S. state of Arkansas, the county seat of Garland County, and the principal city of the Hot Springs Metropolitan Statistical Area encompassing all of Garland County. According to 2008 Census Bureau estimates, the population of the city was 39,467.
Hot Springs is traditionally best known for the natural spring water that gives it its name, flowing out of the ground at a temperature of 147 °F (64 °C) . Hot Springs National Park is the oldest federal reserve in the USA, and the tourist trade brought by the famous springs make it a very successful spa town. Since Hot Springs National Park was the oldest federal reserve, it was the first to receive its own US quarter in April 2010 as part of the America the Beautiful Quarters.
The city takes its name from the natural thermal water that flows from 47 springs on the western slope of Hot Springs Mountain in the historic downtown district of the city. About a million gallons of 143-degree water flow from the springs each day. The rate of flow is not affected by fluctuations in the rainfall in the area. Studies by National Park Service scientists have determined through carbon dating that the water that reaches the surface in Hot Springs fell as rainfall in an as-yet undetermined watershed 4,000 years earlier. The water percolates very slowly down through the earth’s surface until it reaches superheated areas deep in the crust and then rushes rapidly to the surface to emerge from the 47 hot springs.
