Yellowstone's Echinus Geyser Roars Back to Life After 6 Years
4 Mar
Summary
- Echinus Geyser, dormant since 2020, erupted in Yellowstone National Park.
- Activity increased on February 16, with eruptions occurring every two to five hours.
- Eruptions reach 20-30 feet and last two to three minutes.
The Echinus Geyser, a notable acidic geyser in Yellowstone National Park, has resumed its activity after being dormant since 2020. This natural landmark in the Norris Geyser Basin began showing signs of life with an eruption on February 7, followed by several more on February 9, 12, and 15.
By February 16, the geyser's activity escalated significantly, with eruptions occurring at intervals of two to five hours, according to the US Geological Survey (USGS). Each eruption lasts between two to three minutes and propels water approximately 20 to 30 feet into the air.
This pattern is reminiscent of its activity in late 2017. The geyser's acidic nature stems from a combination of acidic gases and neutral waters. Unlike many acidic geysers, Echinus's acidity is not potent enough to erode the surrounding rock formations.
Historically, Echinus Geyser erupted frequently in the latter half of the 20th century. Its unique appearance, with surrounding rocks resembling sea urchins, led to its naming. Scientists from the USGS predict that the eruptions are unlikely to continue into the summer months, as the geyser typically remains active for only a month or two before returning to dormancy.
