A large national park, located in the states of Idaho, Montana, and Wyoming. Established on March 1, 1872, and covering 8900km2 (2,219,790.71 acres) it is the first and oldest national park in the world.
Yellowstone is home of the grizzly bear and wolf, and free-ranging herds of bison and elk. It is the core of the Greater Yellowstone Ecosystem, one of the largest intact temperate zone ecosystems remaining on the planet.
The human history of the park dates back 12,000 years. It was known to the aboriginal natives as "Mitzi-a-dazi," the "River of Yellow Rocks," because of the high sulfur content of the rocks exposed in the river's canyons.
Yellowstone is the largest volcanic system in North America. It has been termed a "supervolcano" because of the three very large caldera-forming explosive eruptions it has experienced in the past 2.1 million years.
Yellowstone is probably one of the most popular national parks in the US. The park is unique in such a way that it features multiple natural wonders all in the same park. You can find geysers, hot springs, a grand canyon, forests, wilderness, wildlife and even a large lake inside the park. Due to the diversity of the features in the park, the list of activities for visitors is endless. From backpacking to mountaineering, from kayaking to fishing, from sightseeing to watching bisons, mooses, and elks wandering into the parking lot of the visitor centers, most visitors enjoy a memorable experience in nature.
Due to the geo-thermal activities under the park, the odor of sulphur is common around the park. Visitors with respiratory difficulties should consult their doctors before visiting.
Wildland fire is common in the park. One major wildfire some years ago burnt down much of the forests in the park. It would be wise to check the status of the park before planning a trip.
