Which of these site types will be least visible in satellite imagery and aerial photographs? Select one: 1. Historical farmhouses 2. Settlements surrounded by defensive ditches 3. Stone Age campsites 4. Iron Age stone-walled settlements

Among the site types listed, **Stone Age campsites** are likely to be the least visible in satellite imagery and aerial photographs. This is because they were typically made with temporary structures, often using natural materials that blend in with the landscape, and left minimal archaeological features. Conversely, historical farmhouses, settlements surrounded by defensive ditches, and Iron Age stone-walled settlements would have more distinct and permanent features that would be more easily identifiable from above.
