Wyoming. This state is most famous for its two outstanding National Parks : Yellowstone and Grand Teton.
Yellowstone is one of the two National Parks in Wyoming. The other one is Grand Teton. Without doubt Yellowstone is the most famous one of the two. It is located on top of a super-volcano caldera. Many geo-thermal features, streams, waterfalls and gorges can be seen there. Simply breathtaking.
Grand Teton National Park includes the major peaks of the 40-mile-long (64 km) Teton Range. It is named for Grand Teton, the tallest mountain in the Teton Range. The naming is attributed to early 19th-century French-speaking trappers—les trois tétons (the three teats) was later anglicized and shortened to Tetons. At 13,775 feet (4,199 m), Grand Teton abruptly rises more than 7,000 feet (2,100 m) above Jackson Hole, almost 850 feet (260 m) higher than Mount Owen, the second-highest summit in the range.
