description Monument Geyser Overview
Monument Geyser is a hydrothermal feature in the Gibbon Geyser Basin of Yellowstone National Park. It is distinguished by siliceous sinter, a mineral deposit formed when hot spring water leaves dissolved silica behind, creating monument-like structures around the feature. Despite its name, the basin has no active geysers, so Monument Geyser is chiefly of geological and historical interest rather than a regularly erupting attraction.
