Brief Park History

The discovery of petrified wood in the park area dates back to 1851, found by Captain Lorenzo Sitgreaves. Then in 1853, Lieutenant Amiel Whipple documented the petrified wood that’s now included in the park. In December 1906, the area was declared as a “Petrified Forest National Monument” by President Theodore Roosevelt. From that time forward, construction began in and around the area, adding a museum, the Painted Desert Inn, bridges, roads, trails, etc. In December 1962, an act of Congress established the Petrified Forest National Park, doing away with the monument status. Although a president can establish a national monument, only Congress can declare a place to be a national park.

Facts about Petrified Wood

Petrified Forest National Monument
Petrified wood is wood that has been turned to stone, or quartz crystal which is brittle and shatters. Petrified wood is harder than steel even though it is fragile. The petrification process begins when wood is covered with water and mud that contains volcanic ash. A chemical reaction occurs that encases the wood in quartz crystals and eventually turns it to stone, a process that can take over a million years to complete. The beautiful color schemes of petrified wood reveal the chemistry of the petrifying groundwater. Manganese, copper and iron in the water or mud during the petrification process give the wood a combination of different color ranges.
