Description
The park features a configuration of boulders along the south bank of the Snake River, known alternatively as Massacre Rocks, "Gate of Death", or "Devil's Gate". Emigrants gave this name to the narrow passage of the trail through the rocks, from the fear of possible ambush by Native Americans. According to diaries of emigrants, settlers in five wagons clashed with Shoshone
The Shoshone or Shoshoni ( or ) are a Native American tribe with four large cultural/linguistic divisions:
* Eastern Shoshone: Wyoming
* Northern Shoshone: southern Idaho
* Western Shoshone: Nevada, northern Utah
* Goshute: western Utah, easter ...
just east of the rocks on August 9–10, 1862. At least eight emigrants from four wagon trains died, with at least 20 Shoshone also killed. The skirmishes took place east of the park and not at Devil's Gate as commonly believed. Some confrontations may have occurred there, but they remain unverified. The Clark Massacre of 1851 occurred just west of Massacre Rocks, closer to the Raft River
