Grand Prismatic Hot Springs The Grand Prismatic Hot Springs are the largest hot springs in the United States, and the third largest hot springs in the world. The colorful effects created by thermophiles living in the hot water and minerals expelled from this hot spring are beyond magnificent. Thermophiles are microbes that thrive in high temperatures, giving many high-temperature features in the park their colors. These vibrant colors can be observed especially in the Grand Prismatic Hot Springs, and at the right time of day, in the misty, steaming air above them.
Mammoth Hot Springs Mammoth Hot Springs is a captivating geological feature that sits at an elevation of 6,735 feet, creating cascading terraces of steaming white, copper, and caramel-colored travertine that flow around and down the slopes of Terrace Mountain. Aside from its own unique features, the views from atop this epic natural wonder include the Gallatin Mountain Range, Mount Everts, Bunsen Peak, Fort Yellowstone and the Mammoth Hot Springs Historic District.
Norris Geyser Basin The Norris Geyser Basin contains the Steamboat Geyser, which is the world’s tallest active geyser with a recorded peak height reaching just over 400 feet. The Norris Geyser Basin is home to a steaming and bubbling landscape that includes hot springs, mudpots, fumaroles, and geysers which tourists may meander through on strategically placed boardwalks across the terrain.
Old Faithful Geyser Situated in the Upper Geyser Basin at the southern end of the park, amidst 150 other geysers and hundreds of hot springs, famous for its eruption predictability, the Old Faithful Geyser boasts eruptions between 100-200 feet in height, with a magnificent, billowing plume extending high into the open air above its eruptions.
