Back to working in ELT3 in Tsaghkahovit. It's appearing that the floor in the southern half of the trench is a hard clay gravelly surface. There's a cluster of decomposing structures where the anomaly showed up. In the northern half of the trench, we dug down to bedrock, orange soft clay, and leveled it off. From this depth, you can see the gravelly possible cultural level in profile. If this is a cultural level, this is the only one since it's resting on sterile bedrock. This floor layer will be loc 3; though the floor is visible in profile and on the surface in the southern half of the trench where I left it intact, the loc 2 wash layer is measured as going deeper since in the northern half since I collected artifacts in this half as locus 2 until bedrock (loc 4). Hopefully this won't cause and major confusion. After taking photos of the loc 3 floor in southern half, I scraped it down some more in search of a burn layer that may have caused the anomaly, but only succeeded in exposing more of the decomposing outcrop that apparently is resting on bedrock. I can't explain it geologically, but this is exactly where the anomaly appeared so much be the cause of it. There was some redness in the decomposing outcrop, which may suggest it was fire effected, or perhaps has a greater iron contact that gave of the big signal.
