While Alaska looks big on a map, that simple visual doesn’t really do the state justice. The state is 663,300 square miles, meaning that it is more than 2.5x the size of Texas. Alaska actually takes up as much space as a fifth of the rest of the US.
The Mercator map we are used to seeing in school actually compresses a good portion of the land to fit it on the page, so the state is quite different from what you are used to looking at.
While Canada separates Alaska from the United States, it is possible to get there by land. The most direct route is the Alaska-Canada Highway that connects Alaska to the lower US. It is about 1,300 miles from Washington State to the first major Alaskan city centers.
