    Default The Stone Forest

    These sections of petrified logs are old, very old. Approximately 225 million years ago, during the Triassic Period, a floodplain existed here, littered with fallen trees. Periodic flooding buried the logs beneath layers of silt. Over time, silica-laden waters filtered through these deposits and petrified the wood by encasing the trees' organic material with minerals. Iron oxides give petrified wood its distinctive red, yellow and orange hues; manganese oxides produce blues, purples and deep blacks, while the original carbon produces the shades of gray. Centuries of erosion have washed away concealing sediment deposits to expose these remnants of the old Triassic woodlands. I always look at petrified wood to see how well the original log shape, the bark and texture were preserved. I also look for the sometimes bright mineral colors that may now be part of this ancient and now stone forest.

    Fascinating, EB. I have a stove-wood sized piece (about a foot long and 6 inches in diameter) that some long-lost relative picked up or purchased back when no one gave any thought to leaving these things alone. This would have probably been back in the 20's or 30's. It is even sawed off flat on both ends. We always had a woodstove, and my father would delight in putting it on top of the woodpile next to the stove, and asking an unsuspecting guest to put a couple pieces of wood in the stove. They'd try to pick it up, and of course exclaim in surprise at the weight, and he'd laugh! Ah, memories. Said piece of petrified wood now holds pride of place as a doorstop here in my office.

    E B -- Excellent to include these, and your explanation is spot-on. Only detail one might add is that, unlike most fossil preservation, with petrified wood it is a matter of total replacement of the original. This happened as a particle of wood was leached away by ground water and a particle of mineral occupied its place (happening at the molecular level). Eventually, all the wood was replaced by minerals, leaving a perfect stone cast of the original, growth rings & all!

    Nate, the woodpile thing is Great! ~Ken

    Thumbs up Re: The Stone Forest

    EB , interesting photo's of the side cuts and the colors of deposits . An early chemist would delight in the analysis of minerals. Polished would make awesome end table tho hard to move. cheers Pete

    Thank you.

    You might consider pricing having the ends pollished. That often reveals a lot of detail and color and may result in your piece being worth some money.

    I love the 2nd one, which really shows the roack-into-wood effect.

    Thank you. A similarly sized piece took three days to cut a flat section of the end off and three weeks to polish but looks absolutely beautiful.

    Yep. A good quality piece of petrified wood can be worth quite a bit of money when cut and polished properly.

    Never seen this before. Quite amazing, and you brought it to me through an Olympus camera.
    Cheers, and God bless

    EB -

    Amazing array of colors in both images, nicely done as always. Also, thanks for the explanation and one question, were these in a park or out in the wilds?
    Best Regards, Jim

    Thank you. These pieces are inside Petrified Forest National Park and are part of the large outdoor museum display which has a nice walk and any number of pieces of wood that I like. There are large numbers of pieces outside the park, but access is slightly more difficult because of lack of good parking and the necessity to walk considerable distances over rough ground.

    Glad you enjoyed it. There are actually large fields, measured in miles, of these pieces of petrified logs. Most are broken into segements a few feet long but some are still in the form of long tree trunks.

    Good shooting,
