Yellowstone National Park in Park County, Wyoming — The American West (Mountains)
The massive cone is a sign of old age. Eruption after eruption, probably for thousands of years, scalding water has deposited this silica mineral formation. By contrast, Old Faithful’s fledgling cone may only be a few hundred years old.
Castle Geyser has dramatically changed its surroundings. By flooding the area with hot, silica-rich water, the geyser has devoured part of a pine forest and turned it into a thermal desert. Tree skeletons are entombed within the cone.
Castle Geyser’s eruptions are predictable; two per day are typically recorded.
Erected by Yellowstone National Park.

More about this marker. The background of the marker features a watercolor painted in 1872 by Thomas Moran depicting Castle Geyser. Vandalism has since destroyed some of Castle Geyser’s original symmetry. Elsewhere on the marker is a sketch of Castle Geyser done in 1870 by Walter Trumbull, a member of the Washburn expedition.
