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.
Uncertain Geyser is an uncommonly erupting feature in the Sawmill Group of Yellowstone’s Upper Geyser Basin. It erupts from a moderately small hole in the geyserite platform on the southern side of Sawmill Geyser. Uncertain can have solo eruptions or erupt in concert with adjacent Sawmill Geyser.
Clip 1 - Uncertain Geyser’s 2:18 to 2:23 PM eruption on 9 August 2025.
