Economic Geyser
geyser in the Upper Geyser Basin of Yellowstone National Park
Economic Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park in the United States.
Economic Geyser is a small, usually inactive geyser located between the Giant Geyser group and the Grand Geyser group. Economic Geyser was once a popular, frequently-erupting geyser until it became essentially dormant in the 1920s.
Economic Geyser is believed to be named for its behavior during its active days. It is reported that most of the water ejected drained back into the vent after the eruption, thus making the geyser appear to conserve its water. It was most likely named by Frank Jay Haynes, the park photographer from 1883 to 1916.
The temperature of the water in geyser pools and other geothermal features can be judged by the color of the bacteria living in the water. Changes in the size and color of bacteria mats at Economic Geyser imply that the geyser is heating up. Photographs of the geyser vent taken in the 1990s show a quiet pool very dark with algae. Photographs of the vent taken in 2006 show a pool of clear water with traces of the bacterial colors associated with higher temperatures.
This brief starts where responsible research should: with the source description of “Economic Geyser” as geyser in the Upper Geyser Basin of Yellowstone National Park. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as geyser in the Upper Geyser Basin of Yellowstone National Park. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q2738252. Authority coordinates are 44.468, -110.838. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1883, 1916 and 2006.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
