Pink Cone Geyser (12 August 2025)
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.
Pink Cone Geyser is the namesake of the Pink Cone Group in Yellowstone’s Lower Geyser Basin. The vent is surrounded by a low, nearly symmetrical, moderately steep-sided geyserite cone that is colored dark reddish-brown. The coloration is attributed to manganese impurities. The cone was originally covered in finely nodulose geyserite, but trodding by non-native buffalo and vandalism by people since the late 1800s has removed almost all of it. An eruption usually occurs about once a day (18 to 28 hours or so). Eruption durations are between 1.5 and 2 hours. The latter parts of a Pink Cone Geyser eruption involve alternating water-phase spouting and steam-rich emissions. Forced steam emissions become increasingly common and less forceful near the end of the eruption. Eruption cessations are marked by sustained passive steaming. Occasional, slightly forced steam billowing occurs afterward.
All clips - Pink Cone Geyser’s 5:56 to 7:37 PM eruption on 12 August 2025.
Clips 7-9 - Pink Cone Geyser erupting in concert with Pink Geyser. (time stamp 5:37)
