Bearclaw Geyser (27 May 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).
Bearclaw Geyser is a small feature in the Fountain Group of Yellowstone’s Lower Geyser Basin. It is located 8 meters south-southwest of Twig Geyser’s vent. Bearclaw erupts from two vents, but this area formerly had four vents (see: http://rcn.montana.edu/Images/View.aspx?id=32116). A third, eastern “vent” occasionally steams. Activity at Bearclaw Geyser includes gurgling, small spitting, and small eruptions with heights of less than one foot (usually only several inches high). Gray, irregularly pustulose geyserite surrounds each vent.
Clips 1-3 - Bearclaw Geyser in eruption from 11:44 AM to 11:48 AM on 27 May 2021.
Clips 4-12 - Bearclaw Geyser’s 12:00 noon to 12:09 PM eruption on 27 May 2021. (time stamp 1:09)

Tilt’s Baby Geyser (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.
Tilt’s Baby Geyser consists of a pair of small, elongated vents located about 8 to 9 meters south of Crested Pool’s southern border in the Castle Group of Yellowstone’s Upper Geyser Basin. Before 2016, the geyser was located immediately adjacent to the tourist boardwalk and could be easily viewed from above. In 2016, the boardwalk was moved away from the feature. Tilts Baby used to erupt every ~3.5 to ~6.5 hours, but intervals have been decreasing in recent years. In 2021, intervals were about 1.5 hours and in 2022 to 2024, intervals were between a half-hour and an hour. Before an eruption, the water-filled and overflowing basin engaged in occasional, very slight pulsing. As an eruption neared, heavier and more frequent pulsing occurred. Eruptions started with very heavy pulsing and energetic roiling, with bursting splashes from both vents starting up soon afterward. Eruptions lasted for about 3 to 6 minutes (sometimes a much shorter eruption occurred that was about 1 minute in duration). The northwestern vent is the more energetic of the two. After an eruption, the basin’s water drained away. When Tilts Baby had longer intervals, the basin slowly filled with water about 1.5 hours after an eruption, and eventually started overflowing. Empty-pool starts also occurred.
In late summer 2025, Tilts Baby eruption durations were about 3 minutes and intervals ranged from about 47 minutes to 71 minutes - most were between 50 and 65 minutes. No pools of water were present before or after eruptions. Pre-eruption activity consisted of relatively heavy steaming and subterranean gurgling.
