The grizzly bear, (Ursus arctos horribilis), has become an icon of Yellowstone National Park and of the wilderness in general. For a large portion of Yellowstone visitors, a grizzly bear sighting ranks right up toward the top of the bucket list, alongside witnessing such famous attractions as Old Faithful Geyser, the Grand Canyon of the…

Photo courtesy Montana State University Thermal Biology Institute. When I, Leysa, take my guests on tour I demonstrate how the seemingly little things in Yellowstone contribute to the bigger picture. For example, how small grubs, insects, and ground squirrels can feed some of the park’s biggest carnivores; how removing one apex predator can change an…

One of the last days of June and the dash tells me it’s 38° F at 6 a.m. Awesome! That is exactly what I want on a morning drive to the center of a volcano. Geyser steam hangs thick in the air like cream of mushroom soup and Yellowstone is virtually deserted. As we drive…

“Oooooh, this might be the one!” I lost track of how many times we had said (or thought) that in the past three days. But this time it really did look like a more substantial minor eruption than any of the previous ones. Alas, the minor eruption (or “minor” for short) fizzled out and we…

The Yellowstone Floods of 2022 served as a stark reminder of the complex relationship between extreme weather events and climate change. As we witnessed—and continue to witness—the impacts of climate change worldwide it has become imperative for all of us as individuals, communities, businesses, and governments to take decisive action to curb greenhouse gas emissions…

  As a naturalist guide in Yellowstone, one of the most coveted sightings as far as wildlife is concerned is to catch a fox hunting—or “mousing”— for its prey. However, because of foxes’ tendency to be more active at night, this sighting can prove to be a difficult challenge. On an early Sunday morning in…

Day after day, month after month, year after year, familiar faces show themselves in Yellowstone. For some, this means people: the wolf watchers, those individuals with the largest spotting scopes of all that we’ve grown to love and admire throughout time; the geyser geeks in their floppy sun hats, letting us know when our favorite…

Something about sandhill cranes catches our attention in northern Yellowstone. The cranes fly up to 200 miles per day when migrating north to their spring nesting grounds here, announcing their arrival in an insistent and raspy chorus. Their unmistakable calls — made possible by long windpipes that curl into their sternums, adding richness — can…

May is a fabulous time to view grizzly bears in Yellowstone!  In this video a mother grizzly and her two 2.5-year-old cubs play and wrestle in a small snow patch on Yellowstone’s famed Northern Range. This level of somewhat violent play may be the beginnings of mom pushing the young ones out on their own….
