Three Vent Geyser (2016-2024)

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).

Three Vent Geyser is located in the western part of the Kaleidoscope Group of Yellowstone’s Lower Geyser Basin. It occurs about halfway between Kaleidoscope Geyser and Pair Geyser. As the name suggests, three vents are present - its largest vent is located at 44° 33’ 15.56” North latitude, 110° 48’ 48.33” West longitude (see: http://rcn.montana.edu/Images/View.aspx?id=33533 ). In 2014 and 2015, Three Vent Geyser was mostly inactive, with occasional low roiling and low to moderately low doming eruptions. Decent-sized, bursting eruptions from Three Vent Geyser were reported in 2015, 2016, 2017, 2019, and 2024. Most eruptions appear to be originating from the "4B Vent" of Keller (2005) - GOSA Transactions 9: 121-133, but the A Vent and the C Vent also have occasional activity.

$Cinnamon Spouter & West Cinnamon Geyser (2026) Cinnamon Spouter & West Cinnamon Geyser (2026) 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. Cinnamon Spouter and West Cinnamon Geyser are located in the Black Sand Basin of Yellowstone’s Upper Geyser Basin. Cinnamon Spouter’s irregularly-shaped basin is 3 to 4 meters in diameter, with a centrally-located and irregularly-shaped vent area. West Cinnamon Geyser is located on the southwestern side of Cinnamon Spouter and has a subcircular basin 2 to 3 meters in diameter, with a ~1 meter diameter inner crater. Cinnamon Spouter first appeared in the late 1980s, under a tourist boardwalk. Early activity consisted of periodic geyser eruptions. The long-term, normal behavior of Cinnamon Spouter has become moderately low perpetual spouting that reaches about two meters high or less (usually much lower). After individual periodic eruptions occur in adjacent West Cinnamon Geyser (for example, in 2016), Cinnamon Spouter’s water level lowers and runoff ceases. Low-pool perpetual spouting can continue or activity can cease altogether, with water draining out of sight. Runoff water from Cinnamon Spouter drains to the south and southeast toward Iron Spring Creek. In 2025 and 2026, the distal runoff channel was completely dry - overflow was no longer occurring. In 1998, researchers measured the water temperature of Cinnamon Spouter at about 75° Celsius, with a pH of about 8.3 (= somewhat alkaline). West Cinnamon Geyser (also known as Cinnamon West Geyser) appeared subsequent to Cinnamon Spouters first appearance in the late 1980s. West Cinnamon Geyser was initially a fracture but has since widened into its present shape. Its normal behavior is low to very low perpetual spouting. It also has 1 to 2 meter tall geyser eruptions that occur in series, with hours- to days-long intervals between series. The first two eruptions in a series pour out large volumes of water for such a small feature. Water runs off toward the south and southwest and percolates downward into the siliceous sinter gravel. In August 2026, Cinnamon and West Cinnamon were erupting as perpetual spouters, but West Cinnamon’s splashing energy cycled from quite mild to fairly energetic (“eruptions”).
