This week in Yellowstone National Park, from September 11th through September 17th, 2025, I will tell you how elk self-anoint themselves, share a trek where you may see bears, tell you a spot north of the park for wildlife watching, and also try to convince you to get out early in the cold mornings. I will also give you the complete weather forecast, wildlife report, the news, and everything else you need to have an incredible time, “This Week in Yellowstone.”
