Jewel Geyser

Jewel Geyser is a fountain geyser in the Biscuit Basin area of Yellowstone National Park and ejects water in bursts reaching roughly 30 feet high. The basin is surrounded by gleaming mineral beads that resemble small pearls and give the geyser its distinctive appearance.

The formation was initially named Soda Geyser during the Hayden Expedition but received the name Jewel Geyser from Arnold Hague in 1887. This renaming reflected the striking mineral and sinter formations surrounding the basin.

The site draws visitors interested in watching regular eruptions and admiring the glittering mineral deposits surrounding the vent opening. The pale sinter beads encircling the basin look like jewels and give this place its distinctive character.

The site is accessible via the Biscuit Basin Trail from the parking area on Grand Loop Road and the path is easy to follow. Eruptions occur regularly, so spending about 15 to 20 minutes watching is worthwhile to see an event.

Each eruption event produces multiple separate water bursts in succession, which sets this geyser apart from others. The water at the vent reaches near-boiling temperatures even though the visible eruptions are not extremely tall.
