A-0 Geyser
A-0 Geyser is a
geyser in the
Lower Geyser Basin of
Yellowstone National Park in the
United States.
A-0 Geyser is part of the White Creek Group which includes
Spindle Geyser and
Botryoidal Spring. It can be identified by its shallow, round basin with a round vent in the middle found 100 feet (30 m) southeast of the
Surprise Pool parking area.
It erupts for a duration of 30–40 seconds with an interval of around 24 minutes between eruptions. The fountain reaches a height of 5–10 feet (1.5–3 m).
The name A-0 is an unofficial name based on the proximity of this geyser to the dormant A-1 and A-2 geysers.
