The Grand Prismatic is the thermal feature that is most photographed in Yellowstone National Park and after taking one look at it, it’s easy to see why!
Old Faithful Geyser
Old Faithful is one of 500 geysers located within the Yellowstone National Park in Wyoming but it is by far the most famous of all those geysers. Why is this special geyser named Old Faithful, well because it’s just that faithful. It faithfully erupts on or about on schedule throughout the day.
