The natural geologic area that I am choosing to do is The Yellowstone Caldera, which is located in Yellowstone National Park in Wyoming. Yellowstone Caldera is also known as a “super volcano”. The population count for visitors Yellowstone National Park is 308,138,711 people; it was last updated in June of 2014 ( Chuck Raasch , 2013 ). Most of the things that attract people to Yellowstone Park are site seeing and beautiful trials. Anybody that visits there shouldn’t leave Yellowstone Park without seeing one eruption from “Old Faithful”. Eruptions last one to five minutes and consist of 3,700- 8,400 gallons of erupted boiling water that reaches 106- 184 feet high (Bruce Gourly, 1997).
Yellowstone has many trails to go exploring through; such as the Geyser Hill Loop Trail, Observation Loop Trail, Black Sand and Biscuit Basin Trail, and many more. This park also has a lot of different wildlife; bison, grizzly bears, mountain goats, mountain lions, and a lot more. They also have strict laws about approaching animals, one in which being you should keep a strict distance away

Yellowstone experiences many natural disasters such as volcanic eruptions, steam explosions, and earthquakes; I am going to focus on the volcanic eruptions and lava flows. Yellowstone lava eruptions were nearly 600,000 years ago, 30 eruptions of rhyolitic lava flows filled the Yellowstone Caldera. The rhyolitic lava is really thick and covers a large portion of Yellowstone. There have only been three eruptions from the Yellowstone Super volcano: 2.1 million years ago, 1.2 million years ago, and 640,000 years ago. The last eruption 640,000 years ago caused Yellowstone to collapse creating a sunken giant crater or caldera (Florian Herrmann,2013).The magmatic heat from that eruption still powers the geysers, hot springs, and mud
