Shoshone Restore Bear River Massacre Site, the Deadliest Slaughter of Native Americans in U.S. History

cultural-heritage · 2026-07-28

On January 29, 1863, the Bear River Massacre occurred in southeastern Idaho, resulting in the deaths of an estimated 250 to 500 Shoshone individuals, including families. Led by Colonel Patrick Edward Connor of the Union Army, this incident eclipsed the fatalities of both the Sand Creek and Wounded Knee massacres. In 1990, the site received designation as a National Historic Landmark, later being renamed in 1993 to honor its painful past. In 2018, Brad Parry of the Northwestern Band of the Shoshone Nation acquired 350 acres to revive the local ecosystem. His historical work earned him the premier Schnitzer Prize of the West.
