This mass of rock plunged from an altitude of approximately 3000 feet (914 meters) down into the waters of Gilbert Inlet (see map below). The retreat of Lituya Glacier in the last century destabilized the eastern slope of Gilbert Inlet and on July 9, 1958, an earthquake triggered a landslide that generated a megatsunami. This was prompted by a letter released by a group of scientists that highlighted the problem.

A minor earthquake magnitude 3.7 (ml/mb) strikes 49 km SSE of Glacier View, Alaska (30 miles) on Monday. The changes that the earthquake effected in the glaciers included a rapid retreat of Muir Glacier, 150 miles to the southeast, and a general advance of several other glaciers near Yakutat Bay. The epicenter apparently was near Rendu Inlet between the east and west arms of Glacier Bay. “It appears that this massive outburst flood traveled underneath the Lituya Glacier, emerging from under its south end onto the gravel delta that now separates the glacier from Lituya Bay,” said National Park Service geologist Michael Loso in a blog post for Glacier Bay National Park. I have just returned from Glacier Bay and I noticed this effect just by looking at the tourist map. Glacier Bay has had other spectacular landslides, including one in 2014 on Johns Hopkins Glacier.
