As I was walking along a desert nature trail, I came upon this unusual feature.  To be honest, I was surprised by its presence.  But then I got to thinking, don’t live things, or those things that were formerly alive belong in a garden?

What do you think it is?  Need some clues?  Here are the first ones:

I was once part of a beautiful semi-tropical forest near the equator…

My current location is quite a ways north of the equator, although I never left the land I origin from…

I was buried in layers of mud until I was unearthed…
I am much heavier now then when I died…
I used to be alive, but that was a long, long time ago…

Volcanoes, wind, and water helped to create what I am today…

When I was young, I was soft enough to be able to be cut with a knife but am now harder than steel…

Much of my color comes from iron…

You can find me in many different areas of the world, (Denmark, Mexico, China, New Zealand, and Indonesia), my home has always been in the land that makes up Arizona…

Parts of me are stolen every year by tourists…

 

Have you figured it out?

Here is the answer…

Did you guess correctly?  These pieces of petrified wood are made up of the remains of trees that are approximately 200 – 250 million years old.  They are no longer made up of any living material.  They are now made completely of stone.  The semi-tropical forest where they once stood in, has since disappeared.

Over 200 million years ago, Arizona was close to the equator, and the climate was much more humid, hence the presence of a sub-tropical forest that the trees originated from, before being transformed into petrified wood.

I came upon these beautiful specimens while I was walking along the Nature Walk, which is located next to the Mayo Clinic in Scottsdale, Arizona.  These specimens were brought here from the Petrified Forest National Park, which is in north-eastern Arizona in the Painted Desert.

More information about petrified wood and their origins can be found here at Petrified Forest National Park.

    I am originally from Central New York State and, when my grandmother passed away a long time ago, among her possessions we found a piece of petrified wood that had hand written on it "Arizona Pet wood 1885." When I pick it up it is always very cool to the touch. I think it is amazing that, over a hundred years later, here I am living in Arizona with the piece of petrified wood back out here and reading your interesting post. My Grandma would be amazed!

    My daughter collects petrified wood. I was so pleased when she called me and told me she had installed her first garden at her new house.

    She had removed all the grass from her garden bed, covered it with weed barrier, then rocks of all sizes from fine gravel to bull rocks. Then she planted her petrified plants! It was beautiful, although surprising to me!

    I guessed petrified wood before getting to the end. We have a couple of pieces picked up over the years. We both love rocks. What a wonderful bit of info. Thanks for sharing it here with us.
