Lassen Peak [SEP] Human history
The areas surrounding Lassen Peak, especially to its east, south, and southeast, represented a meeting ground for Maidu, Yana, Yahi, and Atsugewi Native Americans. The volcano is known among native populations as "Amblu Kai", which means "Mountain Ripped Apart" or "Fire Mountain". Because the area was not suitable for permanent habitation, there is relatively scarce archaeological evidence of a native presence in the Lassen area. The first white man to reach Lassen Peak was Jedediah Smith, who passed through the area in 1821 as he made his way for the western coast of the United States. After the California Gold Rush brought increased numbers of settlers into the area, Lassen Peak was named in honor of a Danish blacksmith, Peter Lassen, who guided immigrants past the peak to the Sacramento Valley during the 1830s.
