The JCB came back today, and as it was working near where our sunshades are normally tethered, we didn't have any shade today.
Nonetheless, we got a lot done -- we took a bit more out near that stone installation, and I think it's become clear that it more or less follows the line I expected it to follow, and we went further down in the robber trench of the big wall.
However, I'll admit that not much of that is visible in this picture; unfortunately, it's the best of a bad lot. But I should be able to get more tomorrow, as we're not planning on doing any additional digging in our square tomorrow. Instead, everyone is going to be in the northern part of the area, cleaning up the rubble that the JCB has knocked loose. So, in addition to reporting on that, I might get somewhat more intelligible views of what we did today.
