This week in Yellowstone National Park, from August 27th to September 2nd, 2026, I'll let you know what to actually expect when visiting the park in September, talk a bit about the importance of obsidian in the park, tell you what is closing in the park this week, and try to explain why seeing a grizzly this time of the year is so hard to do. I will also give you the complete weather forecast, a cool trail to hike, the snowpack update, the wildlife report, and everything else you need to have an incredible time, “This Week in Yellowstone.”
