Bear Creek, an old-growth forest near the northern edge of Yellowstone National Park, is closed after a bear was spotted in the area.
The bear was photographed Wednesday, a day after the park announced a bear ban.
It was spotted by two residents who live nearby and reported the sighting to park rangers.
It’s not clear how long the bear has been in the park.
Yellowstone National Park spokeswoman Amanda Loomis says the park’s grizzly management team is looking into the incident and is working with the National Park Service to determine what can be done to protect the forest.
Yellowistrope Mountain, a popular mountain biking trail in the northeast corner of the park, is also closed because of the bear, and visitors to the park are asked to stay at least 10 feet (3 meters) away from the trails.
The park says visitors are reminded to be aware of bears and other wildlife.
