Alaska includes an area of more than 375 million acres, equivalent to about 570,665 square miles. With coastal waters and rivers added in, the total is more than 640,000 square miles.
Alaska is the largest state in the union, being double the size of Texas, and larger in size than the next three biggest states combined. These states are Texas, California and Montana. Fifty-four million acres are set aside as national parks, and much of Alaska's land mass is comprised of wilderness. Alaska once included four separate time zones, but has now been reduced to two. Additionally, the coastline throughout the state is longer than the entire Atlantic coastline on the eastern border of the United States combined.
Due to its lush wilderness, Alaska is home to many national parks, including the largest nation park in the United States: Wrangell-St. Elias National Park and Preserve. Additionally, Alaska's wild terrain includes the highest mountain in the nation, Mount McKinley, as well as more active volcanoes than anywhere else in the nation. In some areas of Alaska, there is only a 30 percent chance of seeing sunlight on any given day, making it one of the world's cloudiest regions. Despite this rough terrain, Alaska is home to 735,132 people, as of 2013.
