The public discovery of gold in 1874 by the Black Hills Expedition, led by George Armstrong Custer, brought a mass influx of European-American miners and settlers into this region of the Dakota Territory. A group of unsuccessful miners founded Rapid City in 1876, trying to create other chances; they promoted their new city as the "Gateway to the Black Hills"; it was originally known as Hay Camp. The "Gateway" nickname is shared by neighboring Box Elder. In February 1876 John Richard Brennan and Samuel Scott, with a small group of men, laid out Rapid City. It was eventually named for the spring-fed Rapid Creek that flows through it.
