North Angle 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 (northwestern Wyoming, USA).
North Angle Geyser is located in the Sprinkler Group of Yellowstone’s Lower Geyser Basin. The name is from Landis (1989) (Hydrothermal Observations in Yellowstone National Park, 1988, pp. 183, 341). It is the same as UNNG 9 (“unnamed geyser 9”) / vent 9 of Wolf & Paperiello, 1989 (Report on the Kaleidoscope & Sprinkler Groups, pp. 25, 35-36), who objected to the Landis (1989) term. The geyser is located 6 to 7 meters north-northeast of true Angle Geyser (of Wolf & Paperiello, 1989, pp. 25, 29-30), at 44° 33' 15.44" North latitude, 110° 48' 41.50" West longitude (using a summer 2016 satellite photo via Google Earth). This feature acts as a low to moderately low, frequently-erupting geyser - it is not a perpetual spouter. Pauses between eruptions are usually relatively brief. It has been noticed active during all summers from 2014 to 2021.
In June 2018, North Angle was generally having ~2 minute long eruptions, followed by ~2 minute pauses (i.e., ~4 minute intervals, meaning start-to-start). In early August 2018, eruptions ranged from about 2 to 5 minutes long with 4 to 7 minute intervals. In 2019, eruptions were less than 1 minute to about 7 minutes long, with 3 to 9 minute intervals. In August 2020, eruptions ranged from less than 2 minutes to ~3 minutes long, with regular 5 to 6 minute intervals.
In late May and early June 2021, activity at North Angle Geyser had changed. Eruptions were decent-sized for this feature, compared with previous years and were less than one minute long (e.g., ~39 seconds and ~42 seconds). During an eruption of nearby Reverse Firehose Geyser in late May 2021, North Angle was inactive. This inactivity continued for about 40 minutes afterward. Intervals for North Angle on 1 June 2021 ranged from 7 to 10 minutes. On 3 June 2021, intervals were 5 to 8 minutes. On 9 June 2021, ~one minute long eruptions continued, but a ~3 minute long eruption was also noticed, which was long for this season. Intervals that day were remarkably long, ranging from 14 to 24 minutes.
