Alaska Is Big!

You could fit Tennessee into Alaska 16 times! One-fifth the size of the Lower 48, Alaska is bigger than Texas, California, and Montana combined!
Alaska is also far-flung: 5.4 times wider (east to west) and 12.0 times taller (north to south) than Tennessee. From north to south, Alaska measures 1420 miles, the distance from Denver to Mexico City, and east to west 2500 miles, the distance from Savannah, GA to Santa Barbara, CA. See detailed Alaska maps.
Alaska also has the most northern point (Point Barrow) and the most western point (Cape Wrangell, Alaska -- further west than Hawaii) in the U.S.

Water & Coastline

Alaska has 74 times as much inland water (in lakes, reservoirs, and rivers) as Tennessee. In fact, Alaska has 3 million lakes over twenty acres big.
Alaska has more than 50% of the entire U.S. coastline, or 6,640 miles. Tennessee has 0 miles of coastline!

Tennessee has 140 times more people per square mile.
If Tennessee's population density were the same as Alaska’s, only 41,658 people would live in Tennessee rather than 5,841,748 (based on 2003 data).

Alaska’s high point, Mt . Denali (20,320 feet), rises 2.6 miles above Tennessee’s high point, Clingmans Dome, at 6,643 feet.
Not only is Mt. Denali the highest mountain in North America, but Alaska has 15 other peaks higher than any in the continental U.S.

Alaska has 640 sq. miles of land for every mile of paved road. Tennessee has 13 sq. miles of land for every mile of road. In other words, Alaska’s land-to-road ratio is 49.0 times greater.
Only 20% of Alaska’s roads are paved versus on average 91% for the other 49 states. During the long, cold grip of winter, Alaskans build ice roads to traverse rivers and ground that is otherwise too soft to drive.
