-and last #5, leaving us for another 90 minutes, or so, as the eruption diminishes and the geyser becomes quiet again. We were too far away to really hear the distinctive noises--the rumbling and gurgling sounds--that are a 'tell-tale' of an imminant eruption. Some of the geysers even have nicknames--like the lion--but I didn't get to those. Have to leave somethings for another trip!
