Hamilton County is a county located in the U.S. state of Tennessee. As of the 2010 census, the population was 336,463.[2] Its county seat is Chattanooga.[3] The county was named for Alexander Hamilton, the first Secretary of the Treasury.

Hamilton County is part of the Chattanooga, TN-GA Metropolitan Statistical Area.

History[edit]

Hamilton County was formed on October 25, 1819 from portions of Rhea County and Indian land. It was named after Alexander Hamilton,[4] an officer in the American Revolutionary War, member of the Continental Congress, the first US Secretary of Treasury, and one of the founding fathers of the United States.

Hamilton County was the site of an important saltpeter mine during the Civil War. Saltpeter is the main ingredient of gunpowder and was obtained by leaching the earth from caves. Lookout Mountain Cave was a major source of saltpeter during the Civil War. The mine was operated by Robert Cravens, who owned the property where the cave is located. In May 1861, Cravens contracted with the Tennessee Military and Financial Board to deliver 20,000 pounds of saltpeter. On the 24th of the same month, he reported that he had ten hoppers already set up in his cave. Cravens was also mining Nickajack Cave in nearby Marion County. In 1862 he quit mining at Lookout Mountain Cave and rented the cave to the Confederate Nitre Bureau, which mined the cave from June 1862 through July 1863. Mining ceased when Chattanooga was occupied by Federal forces in 1863.[5]

In 1919 James County, Tennessee went bankrupt and became a part of Hamilton County in April 1919.[6] James County had been established by the Tennessee General Assembly in January 1871 and was named after Reverend Jesse J. James.[6]

Geography[edit]

According to the U.S. Census Bureau, the county has a total area of 576 square miles (1,490 km2), of which 542 square miles (1,400 km2) is land and 33 square miles (85 km2) (5.8%) is water.[7] Hamilton County is one of the few counties in the United States to border 10 other counties.[8]

Natural areas of interest[edit]

Raccoon Mountain Caverns is a show cave located 8 miles northwest of downtown Chattanooga. It was originally explored in 1929 by Leo Lambert who developed trails and installed lights and opened the cave to the public on June 28, 1931. The cave was opened under the name Tennessee Caverns. The operators of the cave claim that its explored length is over 5.5 miles.

The Crystal Caverns Cave Spider, Nesticus furtivus, is only known from this one cave. Cave guides will occasionally spot one of these rare spiders and point it out to the tourists.[9]

Ruby Falls Cave is a show cave located on the side of Lookout Mountain in downtown Chattanooga. It was discovered by accident on December 28, 1928 when it was intersected by an elevator shaft that was being drilled to develop Lookout Mountain Cave as a commercial cave. Ruby Falls Cave was intersected at a depth of 260 from the surface and Lookout Mountain Cave was reached later at a depth of 420 feet below the surface. The entire project was the work of cave developer Leo Lambert. He named the new cave's waterfall after his wife Ruby, hence the name Ruby Falls. The lower cave, Lookout Mountain Cave, opened to the public on December 30, 1929. Ruby Falls opened to the public on June 16, 1930. Ruby Falls Cave, with its spectacular waterfall proved the more popular of the two caves and it is the only one open to the public at the present time.[10]
