Reverse Firehose Geyser (2021)
Geysers are hot springs that episodically erupt columns of water. They occur in few places on Earth. The highest concentration of geysers anywhere is at the Yellowstone Hotspot Volcano in northwestern Wyoming, USA.
“Reverse Firehose Geyser” is a nickname applied to an otherwise unnamed geyser in the Sprinkler Group of Yellowstone’s Lower Geyser Basin. The name is in reference to the relatively tall, angled, slender eruption columns of Firehose Geyser in the 1990s, which is in the nearby Kaleidoscope Group. Firehose Geyser erupted at an angle, to the right, as seen from the Fountain Group tourist boardwalk. Reverse Firehose Geyser also erupts at an angle, to the left, as seen from the same area.
Based on observations with binoculars, zoomed-in videos, satellite photos, and sight lines, Reverse Firehose Geyser is vent 4 of Wolf & Paperiello (1989, Report on the Kaleidoscope & Sprinkler Groups, pp. 25, 26, 31, 32). This vent is located at 44º 33’ 15.30” North latitude, 110º 48’ 41.43” West longitude. Few eruptions have been reported. Three eruptions were observed on 30 May 2019, one on 7 June 2019, and two on 13 June 2019. Two closed intervals (= eruption start to eruption start) were obtained: 1 hour, 41 minutes and 1 hour, 47 minutes. Three durations were obtained: ~3 minutes, ~4 minutes, and ~4 minutes. The highest water of Reverse Firehose’s eruption column reached over ~40 vertical feet. Vent 4 was also active in 1989 - the geyser and its eruptions are described in Wolf & Paperiello (1989).
The eruption seen here occurred in the afternoon of 27 May 2021. Its duration was about 23 minutes and consisted of one main “burst”, followed by 8 pauses and restarts. The first “burst” was about 9 minutes long. Subsequent restarts were about 1 to 2 minutes long each with eruption columns of lesser height. Blipping at the vent was seen for about 8 minutes after the end of the eruption.
