Old Faithful Geyser, Yellowstone National Park, Wyoming 

This cone geyser erupts almost at predicted time every 44 to 125 minutes, and we witnessed its fantastic eruption while we were visiting its site.
It’s located at Upper Geyser Basin and its eruption height can reach up to 106-185 feet (32-56m). At once, it discharges 3,700 to 8,400 gallons of water. It’s duration can be between 3 and 10 minutes. We witnessed one over 3 minutes long.
