Mmm...nope I am not a butt shooter (or am I??). Ta Prohm is one of the major temples of Jayavarman VII - in fact, a temple-monastery. Ta Prohm features a set of concentric galleries with corner towers and gopuras, but with many other additional buildings and enclosures. The complexity of its layout is increased by its partly collapsed state, with trees interlaced among the ruins. This particular root resembled a butt as you can see from the curves. I didn't notice it until someone told me this and I just have to have a shot of it, since `rear shots' is also one of my specialty.
