United States Coastline

Question

Is it true that more than half of the coastline of the entire United States is in Alaska ?

Answer 1

I doubt it, Texas has quite a stretch of coast as does Florida, California, the Carolinas (both North and South), Virginia, Maryland, Massachusetts, New York, Rhode Island...seems unlikely Alaska has half of all of that!  

Answer 2

It is true!  Alaska's coastline makes up 53.6% of the total U.S. coastline.

U.S. coastline is 12, 380.2 miles

Alaska's coast is 6, 640  miles

6 640 / 12 380.2 = 0.53634

Answer 3

According to one webpage on Alaska it is.  They may be boasting for all I know.  From the link:

"While the distance between the northern and southern points is 1,420 miles (2,285 km) and the distance between the eastern and western points is 2,400 miles (3,862 km), Alaska definitely does not have a neat rectangular shape. The Aleutian Islands extend out so far from the main body of Alaska that they are rarely shown on maps in their proper location. Not surprisingly, Alaska’s 6,640 miles (10,700 km) of coastline amount to over half of the total coastline of the United States."

Answer 4

More than half of the coastline of the entire United States is in Alaska.
