Petrified Forest

A  detour through Petrified Forest National Park is about a 50-mile drive that traverses geological formations dating back more than 200 million years. 

It is one of the largest concentrations of petrified wood in the world, along with North Dakota, Argentina and Egypt. The tallest fossilized trees in the park are close to 140 feet. 

The park includes the historic Painted Desert Inn, built with petrified wood in 1924 and nicknamed the "Stone Tree House."  It was later refurbished in a Pueblo Revival style. The inn closed in 1963 and was saved from demolition in 1975. It reopened in 2006 but does not host overnight guests.

An elderly Navajo weaver was demonstrating her craft on a recent visit to the inn. There's also an ice cream shop on the bottom level that's a nice treat on a hot day. 

Petrified Forest is the only national park that had a stretch of Route 66. A section of the road north of the Visitors Center was plowed under but broken bottles and other debris from Route 66 motorists is scattered on both sides of the old road alignment.

There are no campgrounds but backcountry camping is allowed with a permit within the park.

​ Westbound motorists on Interstate 40 should use Exit 311 to visit the park. Eastbound motorists can Exit 285 at Holbrook to reach the park from the south.

The Tepees area of the park includes layers of gray, blue, purple, and green mudstones and sandstones deposited more than 220 million years ago.

Visitors can travel north to south through the park from Interstate 40 to U.S. 180 to Holbrook or enter from the south and return to I-40.

The Painted Desert Trading Post reportedly opened as early as 1942 and closed circa 1956. It is till standing, but barely.

Petrified Forest is the only national park that included a stretch of Route 66. Painted Desert Inn (right), built in 1920, was closed in 1963 and nearly torn down in the 1970s. The inn reopened in 2006 after a major renovation.

The signature fossils in the park are fallen trees in river channels that were trapped in sediment in the Chinle Formation.
