Eruptions of the Yellowstone volcanic system have included the two largest volcanic eruptions in North America in the past few million years; the third largest was at Long Valley in California and produced the Bishop ash bed. The biggest of the Yellowstone eruptions occurred 2.1 million years ago, depositing the Huckleberry Ridge ash bed.

The station recording this pattern of seismicity was called Yellow Rock (YEL), which was approximately 1 km north of the 2004-2008 vent. YEL was removed in 2007 before the advancing Crater Glacier reached it. The YEL site is now under a hundred or so feet of ice.
