Read the following paragraphs and come up with five original conclusions about the information you are given.

Big Bend National Park Big Bend National Park is a national park located in the U. S. state of Texas. For more than 1,000 miles (1,600 km), the Rio Grande/Río Bravo forms the international boundary between Mexico and the United States, and Big Bend National Park administers approximately 244 miles (393 km) along that boundary. Big Bend National Park has national significance as the largest protected area of Chihuahuan Desert topography and ecology in the United States. The park covers 1,251.8 square miles (3,242 km2). Few areas exceed the park’s value for the protection and study of geologic and paleontological resources. Cretaceous and Tertiary fossil organisms exist in variety and abundance. Archeologists have discovered artifacts estimated to be 9,000 years old, and historic buildings and landscapes offer graphic illustrations of life along the international border in the 1800s. Because the Rio Grande serves as an international boundary, the park faces unusual constraints when administering and enforcing park rules, regulations and policies. In accordance with the Treaty of Guadalupe Hidalgo, the park has jurisdiction only to the center of the deepest river channel as the river flowed in 1848. The rest of the land south of that channel, and the river, lies within Mexican territory. The first effort by any government to set aside such protected lands was in the United States, on April 20, 1832, when President Andrew Jackson signed legislation to set aside four sections of land around what is now Hot Springs, Arkansas, to protect the natural, thermal springs and adjoining mountainsides for the future disposal of the U. S. government. It was known as the Hot Springs Reservation. However, no legal authority was established, and federal control of the area was not clearly established until 1877. Yellowstone National Park Yellowstone National Park, set aside by the U. S. Congress as a national park on March 1, 1872, is located mostly in the U. S. state of Wyoming, though it also extends into Montana and Idaho. The park was the first of its kind, and is known for its wildlife and its many geothermal features, especially Old Faithful Geyser, one of the most popular areas in the park. It has many types of ecosystems, but the subalpine forest is dominant. Firehole River courtesy of National Park Service Aboriginal Americans have lived in the Yellowstone region for at least 11,000 years. The region was bypassed during the Lewis and Clark Expedition in the early 1800s. Aside from visits by mountain men during the early to mid-1800s, organized exploration did not begin until the late 1860s. The U. S. Army was commissioned to oversee the park just after its establishment. In 1917, administration of the park was transferred to the National Park Service, which had been created the previous year. 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.
