On our first day in Yellowstone National Park, we watched Old Faithful Geyser erupt and then walked the trail through the Upper Geyser Basin. As we crossed the footbridge spanning the Firehole River, we watched a Bison eat his way toward the river directly across from a fumarole spouting steam at the river’s edge. Two things immediately come to my mind when I think of Yellowstone National Park: Geysers and Bison. The fumarole is not a geyser but it is a common geothermal feaure of Yellowstone. When the Bison entered the water surrounded by steamy fumaroles, I couldn’t help but think this scene was quintissential Yellowstone.
