• Heart Spring - Named by Park Geologist George Marler for its heart-like shape, Heart Spring features stunning icy-blue waters with an average temperature of 184 degrees Fahrenheit. The striking yellow-orange colors around the pool are due to colonies of microorganisms, not mineral deposits.
• Beehive Geyser - Initially appearing as a large beehive, Beehive Geyser surprises with its powerful eruptions, propelling boiling water 100 feet into the air. It erupts for 5 minutes every 10 to 20 hours, often preceded by “Beehive’s Indicator,” which releases a stream of water shortly before.
• Grand Geyser - Known as the most powerful predictable geyser in the world, Grand Geyser delivers breathtaking eruptions that can reach up to 200 feet high. Unlike cone geysers, Grand is a fountain-type geyser, characterized by a pool rather than a cone structure.
• Chromatic Pool - Although smaller at 30 feet in diameter, Chromatic Pool is renowned for its vivid colors, with temperatures around 133.1 degrees Fahrenheit. The center features brilliant blue-green hues, indicating the hottest water, while the outer regions display a spectrum of colors.
• Giant Geyser - Giant Geyser is notable for its towering cone, reminiscent of the Coliseum in Rome, made from geyserite or sinter, and standing approximately 12 feet tall.
