Ponderosa Pine Bark Layers

1 more picture in a note above!

When looking at this tree straight on, you can really appreciate the lovely textures and patterns of the bark, but if you look at the edges of the bark sections, you can see the many layers that make up this tree's bark. I was surprised how much it looks like shale, (click to see a picture) which is a type of fine-grained sedimentary rock. The inset picture is another angle to show the layers.
