Aurum Geyser

From Wikipedia, the free encyclopedia

Aurum Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States.

Aurum Geyser is found on Geyser Hill. Aurum can, at times, be very predictable. Other times, it can be very erratic. Observations have led to the theory that Aurum's activity is linked to the meadow behind the geyser. When the meadow is wet, activity is regular with 3—4 hours between eruptions. When the meadow drys in late summer and early fall, the interval becomes less predictable ranging from 4—7 hours.

Eruptions last about 90 seconds and range in height from 15—25 feet (4.5—7.6 m). An eruption is usually preceded by bubbling in two small vents nearby. On rare occasions, an eruption will be followed by a second smaller eruption 5—10 minutes after the primary eruption.
