In archaeology, baulks are the unexcavated strips of earth left standing between excavation squares or trenches. They serve as reference walls that preserve the stratigraphy (layering) of a site, allowing archaeologists to study soil profiles and maintain spatial control during excavation.
🌍 Definition
- Baulk: A vertical section of earth deliberately left unexcavated between dig units.
- Function: Provides a visible record of stratigraphy, helps control excavation boundaries, and stabilizes trenches.
- Etymology: From Old English balca (“ridge, bank”).
🔑 Archaeological Contexts
- Excavation Grids:
- Sites are often divided into squares (e.g., 5×5 m). Baulks separate these squares.
- They allow archaeologists to “read” soil layers across the site.
- Stratigraphic Control:
- Baulks preserve vertical profiles showing cultural deposits, natural layers, and features.
- Practical Role:
- Provide walkways for archaeologists.
- Prevent collapse of excavation walls.
- Recording:
- Baulk faces are carefully drawn, photographed, and described to document stratigraphy.
📚 Importance in Anthropology
- Methodological Insight: Baulks are essential for stratigraphic excavation, ensuring accurate interpretation of cultural sequences.
- Cultural Identity: Stratigraphy revealed in baulks helps reconstruct occupation phases, construction events, and abandonment processes.
- Comparative Value: Baulks link horizontal excavation (exposing features) with vertical analysis (layering).
In short: Baulks are unexcavated earth strips left between trenches or squares, crucial for recording stratigraphy and maintaining excavation control.
