Excavation Units

Each block in the checkerboard pattern shown here also happens to be an excavation unit, 10 by 10 feet in size, called a square. Each square is named after the grid coordinate of its southeast corner. Moving your mouse over the excavation map displays the square name in the box below. Notice how the names change in accordance with the grid. Because north is at the top of the map, each square's name is taken from its lower-right corner.

A portion of the Occaneechi Town excavation grid. Square 270R20.
