Unfortunately I do not know what kind of tree this is. This is the bark of the tree which seemed to be peeling away. Did not do much processing on this image. I boost the the contrast using Topaz B/W with blending mode luminosity and sharpened with Unsharp mask.
Looks like tit might be a kind Cedar maybe. Interesting tree for sure. Love the different images you are posting with different materials used in each one.
Becky, you are going to have the most wonderful collection of textures when you are done. I for one will be asking "Please Becky can I use it as an overlay?" - lovely detail and fascinating patterns. Love to see your posts.
