We were at Crystal Geyser on Sept 3, 2008. We waited about two hours and saw an eruption. Duration was approx 22 minutes. Interval unknown. Since this was our first time seeing the geyser, I can't compare to previous visits. However, I would estimate the height never exceeded 30 feet. I have attached two pictures for your enjoyment. The location is beautiful and worth a visit on its own. Jenn & Dan Cooke ------------------------------------------------------------ Home Gym Want fast fitness results?
