refers to the subspherical, grape-like geyserite structures around the vent. In 1996, seismic activity resulted in the sparkling spring changing to an active geyser. It erupts for about one minute. Intervals (between each shock) are 3 to 5 minutes. The fountain reaches a height of 10 feet (3 m). Immediately after an eruption, the pool is quiet. With no warning, eruptions start with a broad, moderately noisy burst. Smaller bursting continues for less than a minute. Eruptions may start with a blue bubble, caused by a large steam bubble rising from below the water surface.
