Lituya Glacier is a tidewater glacier in the U.S. state of Alaska. Located at inside Glacier Bay National Park and Preserve, its source is in the Fairweather Range and it feeds into Lituya Bay on the gulf coast of Southeast Alaska.
It played a significant role in the 1958 Lituya Bay megatsunami. Over time, the glacierâÂÂs movement and retreat carved Lituya Bay into a distinctive geographic formation characterized by steep walls, a very deep submerged bottom, and a very narrow entrance to the ocean which created the opportunity for a megatsunami to occur.
The glacier is also the namesake of the Alaska Marine Highway ferry M/V Lituya.
