Great photo of our Volvo EC220 working alongside our Komatsu PC210 opening 50m long trial trenches in early site investigation, of this significant infrastructure project.
We’re happy to have made good progress with our evaluation trial trenching work on the West Midlands Interchange. Our Fieldwork team have been on site since 4th January with two 360-degree excavators. So far, with a team of 18 archaeologists on site, we’ve completed a massive 390 trenches! ⛏️
The West Midlands Interchange is an especially fascinating project for us thanks to the potential for study of burnt mounds similar to those found during our work on Bronze Age burnt mounds at our HS2 Coleshill site. These burnt mounds appear as a rise of heat cracked rounded stones. Burnt mounds are often found in prehistoric landscapes near a watercourse and with a trough nearby. Stones were taken hot and red from the fire to heat up the trough and once cool, were discarded in piles, forming the distinctive burnt mound features we see today.
Burnt mounds are common in the prehistoric archaeological record across south-western, central, and northern areas of England, Wales, Scotland and Ireland. They have few artefacts associated with them and are rarely identified in association with settlements. Associated ‘troughs’ of wood or stone sometimes also survive. Whilst the precise function of these sites remains debated, it is hypothesised they used ‘hot-stone’ technology to heat water in the trough.
