|  The Nation’s Last Frontier:
Known as the “Nation’s Last Frontier”, the Black   Hills saw the convergence between nomadic and agrarian cultures in 1876, late in   the history of America’s western migration to the Pacific. Like with “49ers” to   California, the “59ers” to Colorado, and the "62ers" to Montana, the Black Hills   gained prominence with the confirmation of gold by the Colonel George Armstrong   Custer Expedition of 1874. By 1876 and the unsuccessful effort to keep the   gold-seekers out, the “rush” was on to the “76ers” of South Dakota.  Spearfish Canyon was prominent in this development. First were the trappers   to this impassable gorge, then the timber and the railroad and the   hydro-electric system that opened the canyon, and finally, today’s scenic   Highway 14A roadway. As the antiquated infrastructures that fostered frontier   development are abandoned, decay and vanish, recreation has become the dominant   public interest. Notables:The canyon is rich in culture with the many notable footprints in the   landscape.
