Cauliflower Geyser is a deep clear blue pool surrounded in raised geyserite nodules that resemble the texture and shape of cauliflower. The water level sits just below the major geyserite deposits, but overflows the pool to an outwash channel filled with orange thermophiles. Recently, Cauliflower Geyser has a fairly narrow eruption interval of 30–45 minutes, but like many of the features has a differing history.

Cauliflower Geyser has an average temperate of 174.8°F (79.3°C), an average pH of 7.6, and an average conductivity of 2093 uS/cm.

Geysers

Geysers have constrictions in their plumbing systems that prevent water from moving freely to the surface where heat would escape. Water beneath the constrictions creates a buildup of steam. Eventually the steam pushes water past the constrictions and the geyser erupts.

Use Caution in Hydrothermal Areas

• Stay on boardwalks and designated trails.
• Hydrothermal water can severely burn you.
• Never run, push, or shove.
• Supervise children at all times.
• Do not scratch hydrothermal mats.

You are responsible for your safety.

Think safety, act safely. Yellowstone is a dangerous place.
