b'Environmental geophysics geophysical surveying that has been done recently (well after the Neolithic) in the area around Stonehenge, including the Durrington Walls Henge, a total of 18.4 km2. There obviously is more to do around Durrington Walls.So far the best theory for why the pits were dug is that they marked a Figure 3.GPR cross-section across Feature 8A (one of the interpreted pits). Data were collected using aboundary. One theory is that only certain 250 MHz antenna. Depth is to 3.2 m. Source: Gaffney et al. 2020 people were allowed to venture into the area demarcated by the boundary, and it most likely had something to do with the Durrington Walls Henge. Like all good geophysicists (archaeologists?), the authors recommend that more field work is required to really get to the bottom of this (so to speak).ReferenceGaffney V., et al., 2020 A massive, late Neolithic pit structure associated with Durrington Walls Henge, Internet Archaeology, 55, 47.Figure 4.The extent of large area geophysical surveys around Stonehenge and Durrington Walls and the location of probable and potential features over 5 m in diameter displayed over a digital elevation model.
