Sandi struck up a conversation with a real geyser gazer, Tom Dunn, who with his wife Genean wrote an excellent book on the geysers of Yellowstone (see http://tinyurl.com/nc5kkwa). An interesting, genuine, and informative man, and very nice.
And Great Fountain erupts.
One more of White Dome, as seen from Great. It's an erratic erupter (from ten minutes to three hours) and we got to see it twice this trip.
Genean and Tom Dunn, with your intrepid geyser-gazer-tyro in between.
