Today is the 163rd anniversary of what might be the largest single act of domestic indigenous genocide in U.S. history. The relationship between the native Shoshone and Mormon settlers moving into their homelands in the Seuhubeogoi (Cache Valley), where the Bear River cuts through mountains on its way to the Great Salt Lake, had been increasingly violent. 500 U.S. soldiers enter a Shoshone winter village on this very cold and snowy morning, and slaughter between 250 to 493 children, women, and men. The surviving Shoshone escape the valley. The commanding officer is hailed a hero and promoted. Mormon settlements expand and business flourishes during the Idaho Gold Rush era. In 2008, the Northwestern Band of the Shoshone Nation purchases the site, with plans for an as-yet unbuilt memorial.
