It was in Wyoming that Butch Cassidy and the Sundance Kid made their names as possibly the most notorious outlaws in American history. Lying between Montana and Colorado, where the Great Plains meet the Rocky Mountains, Wyoming is the least populated of all the US states. Its outstanding features are majestic mountains and high plains.

The climate of Wyoming is dominated by its elevation, on average over 2,000 metres (6,500ft) above sea level, and by its distance from the ocean. While rainfall throughout the state is generally low, it is greater in the west than the east because of the mountains.

Dominated by short grass and sagebrush the eastern third of Wyoming is almost treeless and too arid for growing crops, while the more mountainous west has sufficient moisture to support forests of pine. Overall most areas of the state have a general appearance of dryness much of the time, and the main agricultural activity is cattle farming.

Daytime summer temperatures are generally comfortable to warm and, apart from the occasional thunderstorm, are usually dry. Winters on the other hand are long and cold with a layer of snow covering most areas from December to February. In winter, snow accumulates to considerable depths in the high mountains of the Tetons, Wind River and Big Horn.

Wyoming has high levels of sunshine in all months of the year, and summer mornings are generally particularly clear. Wyoming is also quite windy, and during the winter months average wind speeds can reach 50 to 65 kilometres per hour (30 to 40 miles per hour).

In the far north west corner of Wyoming lies Yellowstone National Park, home to two thirds of all the geysers in the world and large areas of prime forest, though much of it was seriously damaged by fires in 1988. Within the park is some of the most impressive scenery to be found anywhere in the United States with lakes, canyons, rivers and spectacular waterfalls.
