The glacier, which has receded over the years, carved Lituya Bay into a unique topographic phenomenon with steep walls, a very deep submerged bottom, and a very narrow entrance to the ocean which created the opportunity for a megatsunami to occur.
A glacier that has retreated in recent years created Lituya Bay as a one-of-a-kind landscape with towering cliffs, an incredibly deep submerged area, and a remarkably narrow entrance to the sea. This unique configuration allowed for the possibility of a colossal tsunami wave forming.
