Yellowstone is the country’s first national park. It is also one of the most-visited and most-recognized wilderness areas. Yellowstone has found itself in the news a lot this year -- and not just because of the 100th anniversary. The park has seen several incidents and accidents involving humans. Many of the events have been reported on social media. Last month, a visitor to Yellowstone put a baby bison in his car because he thought it looked cold. Park officials later asked wildlife experts to kill the baby bison. They said its mother and other bison rejected the animal because of human contact. Then, on June 7, a 23-year-old visitor fell into an acidic hot spring after leaving a marked walkway. This week, another Yellowstone tourist made the park a trending topic on social media. The National Park Service said it fined a Chinese man $1,000 for leaving a boardwalk path in Yellowstone’s Mammoth Hot Springs area.
