As far as I know.....this has never been done. I have many images of White Dome Geyser......even at night.....but this the first reflection image. This is the culmination of a 26 hour sleepless day that ended at 9am this morning after a 5am start on Thursday......sleep is definitely at a premium!
Canon 1D Mark lll with the 17-40mm lens at 17mm on flat tripod at ISO 6400 for 30 seconds at f4 and the geyser was illuminated with a headlamp briefly.
