Painted Desert

The Painted Desert, located within Petrified Forest National Park in northeastern Arizona, is a striking landscape of colorful, layered mesas and hills. Spanning about 346 square miles, the park features semi-desert shrub steppe alongside vividly eroded badlands. It is especially renowned for its fossils—most notably petrified wood from fallen trees that lived during the Late Triassic Epoch, around 225 million years ago.

Puerco Pueblo

The earliest known human inhabitants of Petrified Forest National Park arrived around 13,000 years ago during the Clovis culture period. These early peoples are considered the ancestors of many modern Native Americans.  By about 2,500 years ago, Ancestral Puebloans began farming corn and living in subterranean pit houses in the region. Around 1,000 years ago, their communities evolved to include above-ground masonry homes known as pueblos, marking a significant development in architecture and social organization.

Blue Mesa 

This colorful landscape was formed between about 225 and 223 million years ago, during the Late Triassic Period.  Back then, this area was a low-lying floodplain crossed by rivers flowing from distant highlands. 

A nice 1 mile hike through Blue Mesa is a great way to 

experience those colorful badlands up close.

Therapsids were large reptiles that possessed many 

mammalian characteristics. They were herbivores.

Rauiisuchids ranked as the top terrestrial predator

of the late Triassic.

Behind the museum is an impressive collection of some of the 

largest petrified logs in the park.
