Yellowstone National Park in Park County, Wyoming — The American West (Mountains)
This petrified redwood is a clue to a warmer, damper, more violent Yellowstone landscape. Anatomically the trunk is indistinguishable from present-day redwoods in California.
When a chain of volcanoes erupted here in Eocene times 50 million years ago, they triggered massive landslides into mountain and valley streams. The rolling mix of ash, water and sand buried forests. Before the trees could rot, abundant silica in the volcanic flow plugged living cells, creating “forests of stone.”
Erected by National Park Service.

More about this marker. A picture at the bottom of the marker shows destroyed trees on Mount St. Helens after the 1980 eruption. The upper right of the marker features a photograph of men standing near Yellowstone’s petrified tree and has a caption of “Volcanic ash and mudflows obliterated a living landscape yet preserved this tree for the ages. There were three redwoods standing here before thoughtless souvenir-hunters chipped away the other two. The 1907 photograph shows a second tree in the background (before this trunk was fenced).”
