The Old Faithful Web Cam
sends a new real-time photo of Old Faithful Geyser approximately
every 30 seconds. Although Old Faithful is not the largest or most
regular geyser in the park, it has become a popular destination
because it erupts more frequently than any of the other big geysers.
All predictions are made using a formula that takes into account the
length of the previous eruption. The formula used has proven to be
accurate, plus or minus 10 minutes, 90% of the time.
