Sera Tunn opens sign placement cards and route corrections submitted at each junction at the four-way split at Copper Bend. Before anyone changes a mark, the crew checks a lamp bracket casts a shadow over the lower direction arrow. The vent change period sets the pace of the work.
The page holds 44 signs legible from both the incoming and return passage. Sera Tunn reads the preceding count, 44, before the next line is entered. A number without a date would not tell the next crew what changed.
The repair crew says the arrow is readable at close range. Travelers say they need to choose a branch before they reach the wall. Here the difference is visible between the posted rule and the route, service or shift just beyond the door.
The table records the result and the branches included in the decision. The board recorded the outcome that it retained the current map and published the route walk that supports it.
The shift closes with the source page attached to the board. The next file uses a new date and scope.
