Treasures
Form 11-B:

2. Yellowstone is America's first national park, named after the river that runs through it. Within the park's massive boundaries, visitors can find mountains, rivers, lakes, waterfalls and some of the most concentrated geothermal activity in the world.

3. Yellowstone National Park is located in the U. S
Yellowstone National Park is located in the U.S. states of Wyoming, Montana and Idaho. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872.

4. The first reports of Yellowstone, in the early 1800s, described a place in the northwest corner of the Wyoming Territory where mud boiled, water spouted, and steam came out of the ground.

5. Yellowstone National Park spans an area of 3,468.4 square miles.

6. Native Americans have lived in the Yellowstone region for at least 11,000 years. In 1917, administration of the park was transferred to the National Park Service, which had been created the previous year.

7. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than 1,000 archaeological sites.

8. Yellowstone Caldera is the largest supervolcano on the continent.
The caldera is considered an active volcano. It has erupted with tremendous force several times in the last two million years.

9. The park is the centerpiece of the Greater Yellowstone Ecosystem.

10. Hundreds of species of mammals, birds, fish and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants.

12. Mammoth Hot Spring:
The Terraces, first described by the 1871 Hayden Survey, were given the name of White Mountain Hot Spring, even though they were well known and named before then.
The Mammoth Terraces are constantly changing shape and color.
Along with changes of thermal activity come changes in color.

14. The grand Canyon :
The Grand Canyon of the Yellowstone is roughly 20 miles long, measured from the Upper Falls to the Tower Fall area. The canyon was formed by erosion as Yellowstone River flowed over progressively softer, less resistant rock. The Lower Falls is often described as being more than twice the size of Niagara, although this only refers to its height .

16. The lake area:
Yellowstone Lake is the largest body of water in Yellowstone National Park. The lake is 2,357 m above sea level and covers 350 km2 with 180 km of shoreline.
Yellowstone Lake is the largest freshwater lake above 2,100 m in North America.

18. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls

20. Yellowstone is a national treasure of the U.S.A.
