Geography In Brief (from Wikipedia):
Alaska is the largest state in the United States in terms of land area, 570,374 square miles (1,477,261 km²). If a map of Alaska were superimposed upon a map of the lower 48 states, Alaska would overlap Texas, Oklahoma, Kansas, New Mexico and Colorado. Alaska has the longest coastline of any state.
With its numerous islands, Alaska has nearly 34,000 miles (54,700 km) of tidal shoreline. North America's second largest tides occur in Turnagain Arm just south of Anchorage, which often sees tidal differences of more than 35 feet.
Alaska is home to three-and-a-half million lakes, just counting those 20-acres in size or larger. Marshlands and wetland permafrost comprise another sizable chunk of the state, collectively covering 188,320 square miles, mostly in northern, western and southwest flatlands. Frozen water, in the form of glacier ice, covers still more: some 16-thousand square miles of land and 1200 square miles of tidal zone. One, the Bering Glacier complex near the southeastern border with Yukon, Canada, covers 2250 square miles alone.
