Arbitrary level refers to the fundamental vertical subdivision of an excavation square, implied only when easily identifiable natural strata are absent and when natural strata are more than ten centimeters thick.
Natural strata refer to a vertical subdivision of an excavation square, which is reliant on the natural breaks in the sediments in terms of grain size, color, hardness, texture, or other features.
