Labial’s Satellite Geysers (2023)
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.
Labial’s Satellite Geysers consist of two vents in the northeastern Pink Cone Group of Yellowstone’s Lower Geyser Basin. Eruptions are uncommon and durations are usually 12 to 15 minutes, but range from ~9 to ~17 minutes. Eruptions commence with the eastern vent, which has low to moderate-sized splashing. As an eruption nears completion, the eastern vent’s activity gets lower and weaker. The western vent usually starts after and finishes before the eastern vent. Activity at the western vent is steam-rich with spitting spouts that can reach higher than the eastern vent’s splashing. Minor eruptions are brief (less than one minute) and involve light splashing, spouting, and spitting from the eastern vent. The eruption seen here was preceded by a decent-sized spritz from the western vent about an hour earlier. This eruption started from the eastern vent. The western vent was active for about 3 minutes, with just steaming afterward.
Filmed from Firehole Lake Road. Clips are muted - all that can be heard is annoying wind.
Clips 1-8 - Labial's Satellite Geysers’ 5:06 to 5:20 PM eruption on 11 August 2023.

UNNG-TGG-3 (unnamed Tangled Geysers Group geyser)
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.
“UNNG-TGG-3” is the catalog designation for an unnamed, fountain-type geyser in the Tangled Geysers Group of Yellowstone’s Lower Geyser Basin. The vent is at 44° 32’ 25.76” North latitude, 110° 48’ 17.44” West longitude on the September 2023 satellite photo on Google Earth (it’s at 44° 32 25.86” North latitude, 110° 48’ 17.40” West on the June 2016 satellite photo). The basin has enlarged in recent years. In 2016, it was about 2 meters across and somewhat irregularly-shaped. In 2023, its basin was about 6 to 7 meters across and irregularly-circular in shape.
UNNG-TGG-3 was seen having eruptions on 26 and 30 July 2017 - if it was active in previous years, it was just blipping. In August to October 2025, UNNG-TGG-3 was active again, with eruption durations between 30 and 60 seconds and maximum eruption heights of ~3 meters or higher. Reported closed intervals (= eruption start to eruption start) in 2025 ranged from 51 minutes to 115 minutes.
