Wood is the bone of trees. This is the lost Ponderosa Pine graveyard, where all the old and dying pine trees go to die and collect in huge piles of potential firewood. You can tell this forest is in the desert. There is no evidence of rot or moss or fungus (maybe a little) on any of these limbs. This is the kind of pile you wish you could find when you are camping and want to roast marshmallows.
