Grand Geyser



The above picture shows afterplay from Vent and Turban. Notice Grand's empty crater to in the lower right portion of the picture.

The above photograph shows an afterburst of Grand. Afterbursts occur from an empty crater up to about ten minutes after the end of the eruption. Afterbursts are relatively rare. Also shown are Vent and Turban Geysers during their post Grand activity.
