Yellowstone National Park - markgromko

Solitary Geyser. Some of the geysers erupt with great regularity on a time scale from minutes to hours to days; others range from less punctual to unpredictable. Solitary Geyser erupts about every 8 minutes, with an eruption that lasts only a couple of seconds. We stayed through four cycles and were lucky, finally, to capture it at its peak.
