One of the most popular sites to visit in Yellowstone is the Grand Prismatic Spring. It's popular among people and also for bears as recent visitors at the park discovered when they saw a huge grizzly walking down the boardwalk.
If you're anywhere in Grand Teton National Park, it's a good idea to assume that you're potentially being followed by a bear. That's exactly what happened to a runner in the park recently as he shared video of the encounter.
It's true that some things never seem to change at Yellowstone National Park, but a new family retro video shows that other things have. It dates back to the 1950's and shows how many tourists used to hand-feed bears.
