From my experiences, no-Indicator Beehive eruptions are not a common occurrence, and are something I've seen personally only in winter. At times during the winter, Beehive seems to be on a "hair trigger." When behaving in such a fashion, it exhibits heavy splashing and surging, often giving big, "Herb Warren" type splashes. Occasionally, one or more of these surges in quick succession is enough to touch off an eruption, and the geyser will then "catch" and take off. I've never witnessed a no-Indicator eruption in summer, so I don't know what those are like, or if they're similar to the ones I've seen in winter, or not. Other gazers might have more to share on this. Andrew Hafner -------------- next part -------------- An HTML attachment was scrubbed...
