GRAND GEYSER. This is indeed a GRAND geyser. The trees in the background give you an idea how large this geysers really is. This geyser is located on a boardwalk about 1/2 mile beyond Old Faithful geyser, and yet less than 1% of the people who see Old Faithful take the time to see this truly spectacular sight. It has become a fairly predictable geyser(most one would have to wait is 2 hours.)
Years ago it was quite unpredictable and we once waited over 7 hours to see it erupt-and yes it was worth the wait. To see video of this geyser go the Gary Erickson on facebook.
