Custer is generally considered to be the oldest town established by European Americans in the Black Hills of South Dakota and Wyoming. Gold was found there during the 1874 Black Hills Expedition, conducted by the 7th Cavalry led by Lt. Colonel George Armstrong Custer, a discovery which initiated the Black Hills Gold Rush. It is convenient to major tourist attractions, such as Jewel Cave National Monument, Wind Cave National Park, Custer State Park, and Mount Rushmore National Memorial. The Crazy Horse Memorial is located just north of the city.
