This short walk will take you to an upright petrified tree. Petrified Tree: Subtropical Yellowstone This petrified redwood is a clue to a watmer, damper, more liolent 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 whole forests. Before the trees could rot, abundant silica in the volcanic flow plugged living cells, creating "forests of stone." Volcanic ash and mudflows obliterated a living landscape yet preserved this t ree for the ages. There wer three redwoods standing here before thoughtless souvenir-hunters chipped away the other two. The 1907 photograph shows a second trunk in the background (before this trunk was fenced).
