| Comments: | “Big Sprinkler” vent. Relatively large eruption from westernmost vent in the Sprinkler Geyser complex (Sprinkler Group, Lower Geyser Basin), located at 44° 33' 15.25" North latitude, 110° 48' 39.70" West longitude (using 2016 satellite photos & Google Earth coordinates). This is ~4.25 meters southeast of West Sprinkler Geyser. Eruption from late 1909 to the first quarter of 1911. Very likely a double interval with the 1724 eruption (probably missed one during the Fountain Geyser eruption - obscuring steam). |
