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 about 30 to 40 seconds with intervals of 20 to 26 minutes between eruptions. The fountain reaches a height of 5 to 10 feet (1.5 to 3.0 m).[2]

The name A-0 is an unofficial name based on the proximity of this geyser to the dormant A-1 and A-2 geysers.[2]

The RCN[clarification needed] location of this geyser has been unintentionally switched with Dilemma Geyser, elsewhere in the Lower Geyser Basin.
