1. Giant Geyser Marker
Inscription.
When active, Giant Geyser is one of the largest in the world. Historic accounts describe Giantís eruptions soaring to heights of 250 to 300 feet. However, recent eruptions have ranged from 200 to 250 feet.

Giant Geyser displays cycles of activity and dormancy. The unpredictability of Giant is due, in part, to interconnections between it and the geysers and hot springs of the nearby Grotto Group.

Fast Facts:
ē Giant is a cone-type geyser.
ē When active, Giantís eruptions may reach heights of 200 to 250 feet.
ē Giantís eruptions can last from 1 to 1.5 hours and expel more than a million gallons of water.

Shrouded in Antiquity
The large sinter shroud surrounding Giantís vent may be an indication of the geyserís great age. The slow accumulation of mineral (1 to 2 inches every 100 years) indicates that Giant could be thousands of years old.
