A rainbow rises over Ledge Geyser in Yellowstone National Park, Wyoming. "Ledge is the second largest geyser in the Norris Geyser Basin, capable of shooting water 125 feet into the air. Because it erupts at an angle, however, the water will sometimes reach the ground 220 feet away." - NPS

"Tucked away in the Norris Geyser Basin is Steamboat Geyser, the world’s tallest active geyser. Its major eruptions shoot water more than 300 feet (91 m). Only Waimangu Geyser in New Zealand has rocketed to greater heights—but not in more than one hundred years.

Low fountaining has been active where lava upwells into Halema‘uma‘u crater, at the summit of Kīlauea. This video shows a series of small fountains in the southern portion of the crater floor. Camera shake is due to high winds at the time.

A summit eruption of Kīlauea volcano, within Halemaʻumaʻu crater, began at approximately 4:44 a.m. on June 7, 2023. Lava is flowing on the crater floor and there are several active vent sources. The eruption at Kīlauea’s summit is occurring within a closed area of Hawai'i Volcanoes National Park and high levels of volcanic gas are the primary hazard of concern.
