And, for another geyser that might not be on the list of "major" geysers, but which many gazers spend a great deal of time watching, here's what Marler said about Aurum: "Some seasons this small geyser erupts several times each day; during others it is dormant. The cause of this cyclic activity is presently unknown. An eruption lasts for about 90 seconds; the height is about 12 to 15 feet. Due to dormant periods, it could not be determined if the earthquake had any effect upon it. It has no known underground connections with any other spring." Note it wasn't just that Aurum's intervals got longer in the summer as the standing water in that area on Geyser Hill evaporated, but it was completely dormant. Of course, that might be a source of relief to some of the gazers who only get to the Park in mid-late summer when Aurum has tended to have its really long intervals during the past two decades.
