Recent changes to thermal features closes part of Upper Geyser Basin, Yellowstone

There have been changes afoot to the thermal features on Geyser Hill in Yellowstone's Upper Geyser Basin in the past week, the Yellowstone Volcano Observatory reports.

Ear Spring, a normally docile hot pool, had a water eruption that reached 6 – 9 m (20 to 30 feet) high on Saturday, September 15, 2018.

The eruption ejected not only rocks, but also material that had fallen or been thrown into the geyser in years past, like coins, old cans, and other human debris.

The last known similar-sized eruption of the spring was in 1957, although smaller eruptions occurred as recently as 2004.

As a result of these changes, Yellowstone National Park has closed portions of the boardwalk.
