Alaska - largest state and longest coastline
Alaska is the northernmost state and the largest state by area. Not many people live there on the account that it is quite cold. In fact, school does not get cancelled until it get to be 50 degrees Fahrenheit below zero.
Based on the US 2010 Census data, Alaska does have the lowest population density with 1.2 inhabitants per square mile. For comparison, the average for the United States is 87 inhabitants per square mile.
However, Alaska does not have the least population of the 50 United States. That distinction goes to Wyoming with 563,000 people. Alaska is the 4th least populous state with 710,000 people.
Based on longitude, Amatignak Island in Alaska is westernmost point in all of US territory. That is further west than Hawaii.
The flag of Alaska is quite interesting too. It has eight gold stars in a field of blue. Seven stars form the constellation of the Big Dipper and the eighth star is the North Star.
Barrow Alaska North of Arctic Circle
Some parts of Alaska is north of the Arctic Circle. Barrow, Alaska for example is at 71 degrees latitude, while the arctic circle is at 66 degrees 33' latitude.
That means that certain parts of the year in winter, the sun never comes up. And certain parts of the year in summer, the sun never sets. In Barrow, the sun sets in November 18 or 19 and does not come up again until January 22 or 23rd.
During more than half the year, Barrow is completely overcast.
Nevertheless, the population of Barrow has been increasing from 1880 and peaked at year 2000 with a population of 4,683. The 2010 Census showed an population decrease back down to 4,212. I wonder why?
In any case, more people live in the more well known cities such as Anchorage and Fairbanks, which are the largest and second largest city in Alaska respectively.
What Else In Alaska
Alaska is well known for its annual long-distance sled dog race that happens in early March. The race starts in Anchorage and ends in Nome. The 2012 race was won by musher Dallas Seavey with lead dogs named Guinness and Diesel. They did it in 9 days, 4 hours, 29 minutes, and 26 seconds.

Alaska has famous wild salmon. That is because they do not allow fish farming in Alaska. However, some salmon are spawned in hatcheries and then released into the wild where they are then later caught as wild. [reference]
