Devils Thumb, or Taalkhunaxhkʼu Shaa in Tlingit, is a mountain in the Stikine Icecap region of the Alaska–British Columbia border, near Petersburg. It is named for its projected thumb-like appearance. Its name in the Tlingit language has the meaning "the Mountain That Never Flooded" and is said to have been a refuge for people during Aangalakhu ("the Great Flood").
