Jackson Hole
Jackson Hole is a beautiful valley situated in the state of Wyoming,
USA. The place got its name from David Jackson, a traveler and a hunter,
who once lived there. His friends called it Jackson Hole because it really
looked like a hole in the middle of the mountains.
Jackson Hole is a popular holiday place. In summer month, people go
there to walk in the mountains, ride horses, go fishing and boating on the
rivers and lakes. Many visitors cross the valley in boats on the Snake River.
It turns from side to side, like a snake. The water in the river moves very fast
and you have to be brave to travel on it.
Jackson Hole still keeps its Old West traditions. There are shops with
cowboy hats and boots and cafes which look like saloons of the American
West. Holidaymakers can ride horses or go to a rodeo to see traditional
competitions. The rodeo usually begins with a parade of cowboys and
horses. Then comes the competition. Riders try to stay on a wild animal for
eight seconds. They also ride wild horses and large bulls. The animals try to
throw the cowboys to the ground. The riders try not to fall off. Another thing
that cowboys do is throwing a rope around a young cow’s legs. The cowboy
who does this in the shortest time wins.
