Petrified Forest National Park
Petrified Forest National Park is een nationaal park in het noordoosten van de staat Arizona, Verenigde Staten van Amerika. Het park heeft een oppervlakte van 88.500 hectare. Petrified Forest National Park is bekend door de vele versteende bomen, vooral van de soort Araucarioxylon arizonicum, die zich in het park bevinden en opvallend gekleurd zijn. Maar er worden ook tal van andere fossielen gevonden, zowel van planten als dieren.
Tegenwoordig is het gebied voornamelijk een woestijnlandschap. Dit was tijdens het Laat-Trias, ongeveer 225 miljoen jaar geleden, anders. Enorme bossen met gigantische sequoia’s bedekten laaggelegen moerasgebieden. Vermoedelijk een grote vulkaanuitbarsting heeft dit gebied uiteindelijk verwoest. Boomstammen werden onder water door een dikke laag vulkaanas en modder begraven. Door de jaren heen drong water met silicium, een mineraal dat veel voorkomt in vulkaanas, door in de stammen. Het silicium werkte als een natuurlijke conservering en zorgde ervoor dat het hout in kwarts veranderde. Toen het zuidwesten van de Verenigde Staten begon te stijgen en het huidige landschap werd gevormd kwamen op enkele plaatsen, waaronder in Petrified Forest National Park in Arizona, de versteende boomstammen mede door wind- en watererosie weer aan de oppervlakte te liggen. Op de diefstal van versteend hout worden hoge boetes geheven.

You want to see true beauty? Go here. We drove about 15 miles into the park and it was one exquisite sight after another. Be warned they do not take cash at the gate. You will need a card. Our fee was 25$. The price was well worth the experience and I’d pay it again in a heart beat.

What a fantastic national park to visit that is dog friendly. It is geared towards road touring as you drive from spot to spot and take short hikes to explore each area or viewing point. The roads were in great condition and generally most of the larger sites had restrooms available. It was really majestic place to visit to see all the petrified wood and the painted canyon. I highly recommend folks check it out. There isn't a lot of tree cover or shade so make sure to have sunscreen and have plenty of water.

We had a lot of fun here. They recently extended the hours of the park until 6:30 of you enter by 5. I would recommend more time that just an hour and a half though! Tons to see and do. Get the Navajo tacos at the visitor center before entering the park! They close at 4 so keep that in mind

Cool, unexpected pet friendly stop along I-40! You drive through the park and can pull over at all sorts of turn-outs and viewpoints. There isn't much hiking or walking involved, but you get to see a varied landscape of different rocks!

Very light traffic, not many visitors. Just seeing all the petrified trees peaks your interest to learn more about them and what the area was like 200 million plus years ago. Amazing.

This is great drive-through park. You could do hikes but we just made multiple stops at the scenic overlooks and spent about an hour and a 1/2 in the park and that was great.

The painted desert North portion of the park is spectacular for its colorful overlooks. The many views and short walks from the pullouts in the Southern part of the park through the petrified trees are intriguing and amazing just thinking about what the area must have looked like millions of years ago when it was densely forested.

There are a lot of different things to see in this park. Beware stops can be crowded and not all tourist are polite. We chose some of the spots less crowded and they did not disappoint. No trip is complete without the purchase of a piece of petrified wood. We skipped the park for this and stopped at the Rainbow Rock Shop in Holbrook.
