Continued mag survey in northwest corner of Gate Grid (east side of fortress). Lots of big cobbles that were tossed down from citadel excavations several years ago, which are now making survey difficult in this section of the grid especially on my ankles. And lots of stupid prickly thistle plants that are pretty big and aggressive this late in the summer. Finished blocks 3A-5A, 5B, and 4B. Data file in mag is 15.sstlmnt.wg.
