There's only been one EF4 tornado in Wyoming history and it happened in the summer of 1987. It was a rare monster high-altitude tornado that carved a path of damage from the Teton Wilderness through Yellowstone National Park.
It's not unusual these days to hear someone claim they saw a Bigfoot. It becomes next level when a trained field geologist says they had such an encounter, but that's exactly what happened 44 years ago near Yellowstone National Park.
Yellowstone National Park celebrated its 150th anniversary this year. As the park is already one of the biggest attractions throughout the country, scientists have noted big changes that have been a big part of its upkeep and that have also made it a popular scientific study over the years.
