Lone Star Geyser (2018) - Part II
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).
Lone Star Geyser is the namesake and largest member of Yellowstone’s Lone Star Geyser Basin. It has a moderately large, steep-sided geyserite cone topped with many vents (a former name for this feature was the Pepper Box, in reference to the numerous holes on its upper surface). Lone Star Geyser has both minor and major eruptions. The starts of major eruptions occur about 3 hours apart. Major eruptions consist of continuous vertical jetting of water. This gradually transitions to a moderately loud steam phase, followed by alternating near-quiet and slightly noisy steaming. Quiet, passive steaming occurs after a major eruption. One or more minor eruptions usually occur during the interval between majors. Minor eruptions have continuous jetting of water, but do not transition to a noisy steam phase. Minor eruptions just stop after about 2 to 8 minutes. Major eruptions last about 20 to 30 minutes. Eruption runoff drains southward into the nearby Firehole River along multiple runoff channels.
Clips 1-13 - Lone Star Geyser between eruptions, with preplay splashing and “sloppy minor” eruptions, in the early to mid-afternoon of 8 August 2018.
Clips 14-15 - Lone Star Geyser’s 3:09 to 3:11 PM minor eruption on 8 August 2018. (time stamp 7:16)
