About United States

The United States covers a continent's worth of country, from Atlantic and Pacific coasts to desert south-west, the Great Plains and the Rocky Mountains. New York anchors the east, California stretches down the west coast, the national parks of the Rockies and the canyon country fill the interior, and Hawaii and Alaska add two very different worlds. Spring and autumn are most comfortable across most regions, summer is hot in the interior, and winter covers the north in snow.

The country spans six time zones and covers more than 9.8 million square kilometres, making it the fourth-largest country by area.
