On the evening of Tuesday, October 22, 2024, one of the most iconic grizzly bears in North America, Grizzly Bear 399, was fatally struck by a vehicle on Highway 26/89 in Snake River Canyon, south of Jackson, Wyoming. While we are grateful that the driver did not sustain any injuries, this tragic accident has shaken the ecosystem and the world at large.

The identity of Grizzly Bear 399 was confirmed through her ear tags and a microchip. At 28 years old, she was the oldest known reproducing female grizzly in the region. This particular bear had captivated wildlife enthusiasts, conservationists, and visitors from around the globe for nearly three decades, making her one of the most recognized grizzlies in the world.

At the time of her death, Grizzly 399 was accompanied by her yearling cub, but the cub’s whereabouts remain unknown. There is currently no indication that the cub was involved in the collision, though the U.S. Fish and Wildlife Service (USFWS) is closely monitoring the area to ensure the cub’s safety. Experts are hopeful that the young bear may be able to survive on its own, given that it has reached the age when grizzly cubs often begin to venture out independently. However, the sudden loss is sure to have been a deep emotional blow.

The loss of Grizzly 399 highlights a broader issue — vehicle collisions with wildlife. These incidents are an all-too-common occurrence since highways often intersect critical habitats. When driving through these areas, reduce your speed, especially at dawn and dusk. Follow posted speed limits, and be alert. Always have a second person in the passenger seat to help you look, and make sure to use your high beams. Be extra cautious in fog, rain, snow, or darkness. That way, you can reduce the risk of another tragedy.

The Grand Canyon is one of the world's most iconic natural wonders. Carved by the Colorado River as it flowed over the deserts of Arizona, the chasm stretches approximately 277 miles in length, up to 18 miles wide, and over a mile deep. The canyon's layered red rock formations have been a spectacle for generations, and it's a great trip to have on your bucket list this year. While many might think of the Grand Canyon as a summer destination, that doesn't quite give the whole picture of what this national park has to offer. Grand Canyon National Park is a year-round destination, and the best time to visit Grand Canyon is really up to your goals and preferences.
What to know before you go to the Grand Canyon

Before deciding when to go, there are a few things that you should keep in mind. There is an entrance fee to enter the park, which is currently $35 per private vehicle. Bring your card, because they do not take cash.

Here's something fun about bears — no, we're not telling you how to avoid a bear attack when you're camping. It's time to cast your vote for the chunkiest bear in 2024 as Fat Bear Week returns to Katmai National Park in Alaska! If you're unfamiliar with this annual tradition, you could not have found it at a better time. Fat Bear Week is celebrating its 10th anniversary and promises to be a lot of fun.
Vote for your favorite fat bear at Katmai National Park

The online event started out in 2014 as a way to celebrate some of Katmai National Park's largest creatures as they prepare for hibernation. Bears don't eat or drink while they are in hibernation, so they lose at least one third of their body weight during that time. The fatter the bear, the more likely it is to survive the winter. Their survival depends on gorging on delicacies like salmon from the Brooks River from June to October, and during that time, it's fascinating to watch them put on the weight.
