Yellowstone Volcano

One of the wondrous things about Yellowstone National Park is the realization you’re standing atop a smoldering volcano: the rotten-egg smells of sulfur, the constant gurgling sounds, and the spray of steam in your face.  You’re reminded of this nearly everywhere you visit — surrounded by thermal features such as geysers, hot springs, mudpots and fumaroles.  Among my favorite places to stroll in Yellowstone are the boardwalks and trails that take you through numerous geyser and hot springs areas: West Thumb, Norris, Mammoth, Biscuit, and the jewel of the park the Upper Geyser Basin.
