Today we placed and began excavating Mirak Operation 02. It is placed within the fortress on, what I am hoping is the corner of curvilinear section of wall. Mirak Operation 02 is located on the Northwestern corner of what appears to be a clear room in the middle of the fortress at the top, most Northeastern part of the circular wall that constitutes the fortress. The room appears clearly defined with several linear features that appear to be walls, a depression within them and darker vegetation within the depression. The trench is situated more according to the wall than by cardinal directions. However, it sits on a mostly NE/SW axis. The trench is 3m X 3m with roughly 2m of the NE and SE side within what appear to be the walls and about half a meter outside the wall. The wall itself appears to be about a meter thick but perhaps some of this is collapse. The datum is located about 20 cm from the N corner and is on a large stone that appears to be part of the continuation of this wall outside the trench. The back dirt pile is located about 10m SW and down hill from the trench where there is no visible architecture and it won't hinder potential expansions. We spent the day clearing off the top soil from the trench which was quite a task as the trench was covered in rocks both large and rather small. It is difficult to tell at this point what is wall and collapse. While I am taking the area in front of the wall down another 10 cm at this point it will continue to be Locus 01 until I hit a soil change. Materials included a possible sheep mandible, other bones, many bits of ceramic and some small pieces of obsidian. Tomorrow we will take the trench down on either side of the wall and attempt to define the wall and identify collapse.
