Summary
[edit]DescriptionGray Bulger Geyser erupting (evening, 2 August 2018) 12.jpg |
English: Geysers are hot springs that episodically erupt columns of water. They occur in few places on Earth. The highest concentration of geysers anywhere is in the Upper Geyser Basin at the Yellowstone Hotspot Volcano (northwestern Wyoming, USA).
Gray Bulger Geyser is a cluster of vents near the southern shore of Firehole Lake in the Black Warrior Group of Yellowstone’s Lower Geyser Basin. Over half a dozen active vents occur at & adjacent to the head of a somewhat J-shaped hot spring pool (vicinity of 44° 32’ 38.44” North latitude, 110° 47’ 04.01” West longitude). Some of these vents have been referred to as “Young Hopeful Geyser”, but Gryc (2016) demonstrated that Young Hopeful Geyser is a vent (now usually inactive) just off the end of the hook of the J-shaped pool (at 44° 32’ 38.48” North latitude, 110° 47’ 04.22” West longitude). The most prominent erupting feature in the Gray Bulger Geyser complex is vent 3 of Gryc (2016). In 2014 and 2015, observed eruptions from vent 3 were two to four minutes long with intervals of six to eight minutes (“interval” = eruption start to eruption start). Observations made in June and August 2018 show that Gray Bulger has at least 10 active or potentially active vents. In June 2018, Gray Bulger Geyser was erupting from five active vents (= numbers 1, 3, 4, 5, and 6 of Gryc, 2016). Dominant spouting alternated between vents 3 and 1, with vents 4-6 featuring low splashing. In August 2018, up to 8 vents were active simultaneously. In addition, another active vent is present at the northwestern end of the head of the J-shaped pool - only very low splashing was observed. Reference cited: Gryc, S. 2016 (dated 2015). Firehole Lake geyser delights (but which geyser is it?). Geyser Gazer Sput 29(6): 5-8.
