White Dome Geyser (15 August 2025)

------------------- White Dome Geyser (15 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. White Dome Geyser has one of the largest geyserite cones in all of Yellowstone. It is the most significant and most active member of the Lower Geyser Basin’s White Dome Group. It has an old, large, projecting, whitish gray to pinkish-orangish cone of geyserite (siliceous sinter) that sits atop a larger, low, weathered, paleo-hot spring mound. White Dome Geyser’s eruptions are moderately frequent, originate from a fairly small vent, and are almost always two minutes long - sometimes a little longer and sometimes a little shorter. Eruptions are not predictable, as intervals are rather erratic - they often occur every 20 to 30 minutes or so, but known intervals range from 9 minutes to well over two hours. Short-duration spitting or very low spouting occasionally occurs. Sometimes, "minor eruptions" less than a minute long will occur. Spitting or minor eruptions can ~closely precede a normal eruption. Most eruptions have water reaching about 30 to 50 feet high. Strong winds result in the highest water reaching only 25 to 30 feet high. The highest reported eruption column was about 74 feet above the vent. Clip 1 - White Dome Geyser’s 11:19 to 11:21 AM eruption on 15 August 2025.
