Four months after damaging floods hit south-central Montana, Gardiner’s connection to Yellowstone National Park was restored this weekend.

An Indigenous opera singer has written a song that she hopes will be a new anthem for Yellowstone National Park.

As Yellowstone National Park turns 150 years old, a group of Indigenous artists and scholars is bringing a teepee village and other public art to the park to highlight its Native American history.

When people think of the greater Yellowstone ecosystem, the critters that usually come to mind first are bison, bears or elk. But the park's most prolific organisms are too small to see with the human eye.

“It’s just fun to see them laugh and relax and have fun and realize how much they actually learned," said AP biology teacher Kim Popham, who recently guided her students on a tour of Yellowstone National Park.

Yellowstone is proposing increasing its bison population to as many as 8,000 animals. But Montana is asking that the park withdraw – or at least reconsider – the options it's put forward and come up with new ones.

For decades the park has worked to restore its herds, from fewer than 25 animals in the early 1900s, to more than 5,000 today — enough that the park is now expanding a program that transfers live bison to Native American tribes to help restore populations on reservations.

The season closed Tuesday with 272 wolves killed out of the state’s total threshold of 450.
