This is from East Idaho News Today.
This is terrifying. I have attached an article below. (courtesy of http://www.kxly.com)
All entrances to Yellowstone National Park are temporarily closed due to flooding, rockslides and mudslides on roads.
No visitor traffic heading into the park is allowed, including those with lodging and camp reservations at Yellowstone. Once park conditions get better and park officials can assess the damage, people will be allowed back in the park.
The North, Northeast, West, South and East entrances are all closed. Power is also out in multiple places around the park.
Visitors are recommended to look at road conditions to pay attention to the road status. Many of the park roads will be closed for an extended period of time.
Initial assessments show the roads are washed out or covered with mud. The park is taking further measures to ensure safety, making sure the facilities are working.
