One reason they were ignored? Geysers are volatile. Old Faithful, a popular draw at Yellowstone, erupts every 90 minutes or so, shooting boiling water 100 feet or more toward the sky.

Old Faithful's thermal pools, however, are surprisingly rife with geyser eggs. “This was the largest collection of these rare rocks I have seen in my scientific career,” says Lynne.

In the 1950s, Old Faithful erupted roughly every 60 minutes. But during the time of Hurwitz’s study, there were no big earthquakes, only a pattern of low rain and snow.

New research suggests that how often Old Faithful and other Yellowstone geysers erupt may depend on annual rainfall patterns. Geysers are rare hot springs that periodically erupt bursts of steam ...
