  Black Hole Geyser
Feature Type: Geyser

Lone Star Geyser Basin
Lone Star Group

Black Hole (unofficial name) is a relatively little-known geyser located very close to much better-known Lone Star Geyser, in a small geyser basin reachable by a short trail starting at Kepler Cascades. According to T. S. Bryan's "The Geysers of Yellowstone," its eruptions are highly erratic, with very large variations in durations, intervals and eruption height. Intervals can be as short as 10 minutes, in which case the eruptions only last a few minutes, or as long as several hours, in which case the eruptions too are longer, up to 15 minutes or greater. Eruptions can reach 25 feet in height, although heights of 3 to 4 feet are more common. Relatively little else is known about this geyser owing to its remoteness and a scarcity of reports (the only one at geysertimes.org dates to 2006).

What to look for:
According to Bryan, water rises in Black Hole's funnel-shaped vent anywhere from a few minutes to some hours before an eruption. The eruption itself appears to give little warning once the vent is full. No other information is available regarding precursor events.
