This was taken from the middle of the foundation floor looking northeast.
The scraped lines on the concrete can be seen on the foundation slab and
shows events that were cross-cut.
1. The more impressive lines are in the same direction line as the grooved
lines and the tractor-trailer box in Picture 1. All three are in the west-southwest
to east-northeast direction, marked “A” in Picture 2.
2. The less impressive lines can be seen going at different angles to the
more impressive line. The majority of the less impressive lines are almost
parallel to the right side of the foundation wall, marked “B.”
3. Another line is almost at a 90 degree angle to the foundation wall, marked
“C.” Near to this line the foundation wall is broken.
4. Red paint on the foundation slab is visible.
