Stone Forest: Walking the Yellowstone Petrified Tree
A compact roadside marvel where wood turned to stone—an intimate lesson in Yellowstone’s deep time.
The pullout is modest—just a gravel shoulder and a weathered interpretive sign—but the first step off the asphalt feels like stepping into a time capsule. The air is dry and cool, the pines around you a living chorus. Underfoot, a stump that looks like a sun-bleached log is anything but ordinary: its cells are stone. This is the Yellowstone Petrified Tree, a fossilized witness to volcanic cataclysms and ancient forests, a quiet roadside marvel along the Grand Loop that rewards visitors with a compact, uncanny lesson in deep time.
Trail Wisdom
Carry bear spray
This area is active bear habitat—carry spray accessible at your hip and know how to use it.
Go early or late
Visit at dawn or dusk for softer light and fewer visitors at the pullout.
Wear grippy shoes
The short loop is gravelly; shoes with good tread prevent slips and make kneeling for photos comfortable.
Respect the fossil
Do not touch in ways that could damage it—no chipping, no removal of fragments; leave it for everyone.
