Glacier Bay covers an area of 3,560 km2 of glaciers and accounts for 27% of the Glacier Bay National Park. It was a large single glacier of solid ice till early 18th century. It started retreating and evolved over the centuries into the largest protected water area park in the world. Glacier Bay, on the Gulf of Alaska, was known as the Grand Pacific Glacier about 1,200 m thick and about 32 km in width which has over the last 200 years retreated by 105 km to the head of the bay at Tarr Inlet, and in this process left separate 20 other glaciers in its trail.
