Petrified Tree, Specimen Ridge — Yellowstone’s Eocene Petrified

Petrified Tree at Yellowstone National Park stands as a weathered, towering fossil amid pines and a clear blue sky.

A lone petrified tree stands behind a protective fence, its once-wooden form now stone. Silica-rich groundwater replaced the organic wood over time, a process called permineralization that occurred after volcanic lahars buried the forest 50–55 million years ago. Yellowstone houses one of the largest, best-preserved petrified forests, offering a tangible record of past climates and ecosystems. The scene is a direct glimpse into Deep Time, carved by volcanic activity and forest regrowth.

Access & viewing

GPS Coordinates: 44.91633°N, -110.43939°W
Accessibility: Short path to main Petrified Tree; easy for most visitors; slight incline noted

Conditions & safety

Permits Required: 0

Planning advice

Nearby Attractions: Tower Fall; Specimen Ridge fossil forests
Nearby Facilities: Developed areas offer restrooms and water; overflow parking may occur near Tower Junction
Best Time To Visit: Summer and Fall (June–September/October) after snowmelt; morning light minimizes glare and crowds peak in mid-summer.
Tips Advice: Park early or expect limited parking during peak season.
The short path is easy, but a slight incline may appear.
Use interpretive signs to read the petrified wood’s mineral replacement.
For broader petrified-forest exploring, consider Specimen Ridge hikes with proper gear and bear spray.
Insider Tips: Read the interpretive panel for mineralogical changes in the trunk
Visit in summer mornings to avoid crowds
Explore Specimen Ridge for a broader fossil-forest context

More details

Park Area: Yellowstone National Park
Family Friendly Notes: Keep a safe distance from wildlife; stay on designated paths; read interpretive signs to minimize risk
Attraction Type: Geological Formation
Elevation Feet: 6740
Distance From Entrance: Less than 0.1 miles (278 meters) from the parking area to the tree
Accessibility Level: Drive-up view; short easy path to the tree; slight incline noted
How To Get There: From Tower Junction on Grand Loop Road, head west about 1 mile toward Tower-Roosevelt Junction; Petrified Tree area is just west of Tower Junction.
Parking Availability: Limited capacity; can fill up during peak season
Road Type: Paved Grand Loop Road; short on-site walk to the tree
Seasonal Access: Roads open year-round in Yellowstone, but winter access may be limited by snow
Entry Fees: Varies
Main Features: Single petrified tree; fence-protected viewing area; nearby Tower Fall and Specimen Ridge area
What Youll See: A stout petrified trunk preserved in stone with an interpretive panel nearby; a short, accessible approach from the parking area
Unique Characteristics: One of the largest, best-preserved petrified forests globally; trunks up to eight feet in diameter and some heights over 20 feet; circumference of a noted stump 26.5 feet
Safety Considerations: Wildlife awareness required; stay in designated areas; fences protect the petrified tree; larger petrified forests like Specimen Ridge involve steep, loose footing; bears and wolves may be encountered in surrounding terrain
Best Viewpoints: From the fenced viewing area near Tower Fall, the main petrified trunk sits centered in the view; a gentle slope in front of the tree adds depth to the surrounding terrain.
Photo Opportunities: Close-up shots of the mineralized grain; morning light for softer shadows; backdrop of forested ridges
Photography Spots: Close-up of the fossilized trunk; angled shots to highlight mineral bands; backlit views during golden hour
Sunrise Sunset Quality: Alpenglow potential visible in surrounding ridges during early morning or late afternoon

Frequently asked questions

Do I really need to arrive before 7am to get parking?

Parking is limited and often fills during the peak season; arriving early improves your chance of a spot and reduces time spent circling.

Is it worth a stop for just one petrified tree?

Yes. The short stroll yields a direct look at a fossilized redwood and an interpretation of how volcanic activity and silica mineralization create long-lasting records of past ecosystems.

Can I bring my dog to the Petrified Tree site?

Dogs are not specifically mentioned for this stop; plan around general park rules and keep pets leashed and away from wildlife-prone areas.

Is the path accessible for someone with limited mobility?

Yes. The path to the main Petrified Tree is generally easy, with a possible slight incline; the viewing fence provides a stable, short approach for most visitors.

Is there a restroom at the Petrified Tree site?

Vault toilets may be available at trailheads for extended hikes, but the immediate Petrified Tree stop does not list a dedicated restroom.
