"Located in the northwest corner of Wyoming, with minor areas also extending into Montana and Idaho, is Yellowstone National Park, a U.S. national park. President Ulysses S. Grant signed the Yellowstone National Park Protection Act into law on March 1, 1872, after the 42nd U.S. Congress created it. In addition to being the first national park in the United States, Yellowstone is commonly regarded as the first national park worldwide.The Old Faithful geyser, one of the park's most well-known geothermal attractions, and its fauna are its main draws.Although it encompasses a wide variety of biomes, the subalpine forest is the most prevalent. It belongs to the ecoregion of South Central Rockies forests. Initially, the U.S. Department of the Interior was in charge of managing and overseeing the park; Columbus Delano was the first interior secretary to do so. But in the end, the U.S. Army was given the responsibility of managing Yellowstone for 30 years, from 1886 to 1916.The park was administered by the National Park Service, which had been established the year before, in 1917. More than 1,000 indigenous archaeological sites have been studied by experts, and hundreds of buildings have been constructed and are conserved for their architectural and historical significance. The 3,468.4 sq mi (8,983 km2) Yellowstone National Park is home to mountain ranges, lakes, canyons, and rivers. Part of the Yellowstone Caldera, the continent's greatest super volcano, is covered by Yellowstone Lake, one of the biggest high-elevation lakes in North America. The caldera is regarded as a volcano that is dormant. In the past two million years, it has erupted twice with immense intensity.Because of this continuous volcanism, Yellowstone is home to well over half of the world's geysers and hydrothermal phenomena. The majority of Yellowstone's land area is covered in rocks and lava flows from volcanic eruptions. The park is the centerpiece of the Greater Yellowstone Ecosystem, the biggest remaining almost intact ecosystem in the Earth's northern temperate zone.Yellowstone was designated a UNESCO World Heritage Site in 1978. The Yellowstone River, which gives the park its historical name, roughly divides it in half. The river was given the name Roche Jaune by French trappers near the end of the 18th century, most likely a translation of the Hidatsa name Mi tsi a-da-zi (""Yellow Stone River""). The French name was later translated into English as ""Yellow Stone"" by American trappers. The Native American naming origins for the river is unknown, despite the widespread belief that it was named for the golden rocks found in the Yellowstone Grand Canyon. Native Americans started hunting and fishing in the area at least 11,000 years ago, marking the beginning of the park's human history. The Cook–Folsom–Peterson Expedition of 1869, which included three privately supported explorers, was the first comprehensive trip to the Yellowstone region. The Folsom party arrived at Yellowstone Lake by following the Yellowstone River. In 1870, a group of Montanans organized the Washburn–Langford–Doane Expedition based on the information recorded in the journal kept by the Folsom party members. In addition to Nathaniel P. Langford (after known as ""National Park"" Langford) and a U.S. Army unit led by Lt. Gustavus Doane, it was led by Henry Washburn, the surveyor-general of Montana. The expedition named sites of interest, collected specimens, and explored the area for approximately a month. Eleven years after his initial unsuccessful attempt, Ferdinand V. Hayden was eventually able to explore the area in 1871. He returned to the area with a second, bigger expedition, the Hayden Geological Survey of 1871, which was sponsored by the government. He put up a thorough report that featured paintings by Thomas Moran and large-format photos by William Henry Jackson. The U.S. Congress was persuaded to remove this area from public sale by the report. The Act of Dedication[8], which established Yellowstone National Park, was signed into law by President Ulysses S. Grant on March 1, 1872. By air, the park is 54 miles (87 km) west to east and 63 miles (101 km) north to south. With an area of 2,219,789 acres (8,983 km2; 3,468 sq mi), Yellowstone is bigger than Delaware and Rhode Island combined. Five percent of the land is made up of rivers and lakes, with Yellowstone Lake, at 87,040 acres (352 km2; 136 sq mi), being the greatest body of water. Yellowstone Lake has 110 miles (180 km) of shoreline and a maximum depth of 400 feet (120 m). Yellowstone Lake is North America's largest high-elevation lake, rising 7,733 feet (2,357 meters) above sea level.

Covering 19,623 km2 (7,576 sq mi), Kruger National Park is located in the northeastern South African provinces of Mpumalanga and Limpopo. It stretches 65 km (40 mi) from east to west and 360 km (220 mi) from north to south. Skukuza is home to the administrative headquarters. The South African Republic's government first protected portions of the park in 1898, and in 1926 it was designated as the country's first national park. It is a part of the biosphere reserve known as the Kruger to Canyons Biosphere. Kruger National Park is home to all five of the big game creatures and boasts 147 species of large mammals, more than any other game reserve in Africa. Webcams have been installed to watch the wildlife. There are believed to be just 400 African wild dog packs in all of South Africa, and Kruger is home to packs of these endangered animals. There is a reasonably consistent group of bird species from the park's southern to central regions, but the mopane-dominated flatlands north of the Olifants show a fall in richness.The larger birds of prey, on the other hand, breed during the dry winter, when their prey is most exposed, whereas the majority of species breed during the summer, when rainfall sustain the majority of vegetable and animal food. In 1918, Kruger National Park was declared, and a commission was formed to oversee its development and planning. A government officer named Johannes Andries (Dries) de Ridder served as the commission's first secretary. After 44 years in charge of the Kruger Park, Warden James Stevenson-Hamilton retired on April 30, 1946. Colonel J. A. B. Sandenbergh of the South African Air Force took his post. The government forcibly removed the Makuleke people from the northern portion of the park in 1969, and approximately 1500 of them were relocated to territory in the south so that their original tribal lands could be incorporated into the larger Kruger National Park. The famed Big Five (lion, leopard, elephant, rhinoceros, and buffalo) are among the remarkably diverse species that makes Kruger National Park famous. The park, which spans about two million hectares, draws tourists from all around the world with its unmatched wildlife viewing opportunities.
