Gnarly

Canon 100mm 1:2.8  ISO 125   f/2.8   1/200 sec

I chose to take this in black and white because although the bark was a nice shade of brown I think the textures of this gnarly truck look more effective in monochrome.

Just in case you are wondering what species of tree this is I can tell you...

It is a Metasequoia glyptostroboides  also known as the Dawn Redwood it is a fast growing deciduous conifer which is endangered and apparently the only living species of the genus Metasequoia. It was too early in the season to get a good idea of how it looks in full foliage but I think the bark makes a great image.
