The basin at this convergence of mountains holds one of the highest concentrations of horse owners in the world: folks rely on their horses to care for their cows and to hunt for their winter meat in the backcountry. A flourishing herd of wild mustangs also roam the rolling prairie – a fierce, living tribute to the free spirit and unfenced origins of the horse.
