Explanation:

Many call the purchasing of Alaska, "Seward's Folly" because it was considered at the time that "Seward paid too much for the land."

This is because, at the time of purchase in the year 1867, the United States under the guidance of William Seward the United States Secretary of State bought the Alaska territory for a sum of $7.2million which was considered pricey at the time and thought to be of no use to the United States.

this forms a narrow, steep sided inlet (sometimes deeper than 1300 metres) connected to the sea. the terminal moraine pushed down the valley by the glacier is left underwater at the fjord’s entrance, causing the water at the neck of the fjord to be shallower than the main body of the fjord behind it.
