All the images shown here are slices of an old fallen white oak that had been split long ago such that bark grew along the inside as well as outer edges. Many of the dead standing trees, sometimes known as snag trees, in the Ozark forest where I live have sculptural forms. So do stumps and toppled trees. Their growth in response to environmental trauma, weathering over time, and the work of birds and other creatures that make their homes in the trees, add to the uniqueness of these forms. I love discovering them and watching how they evolve, occasionally adding my own touches.
