Abstract: |
A seven-trench evaluation was undertaken at Land at Lockesley Drive, Orpington. All trenches were excavated to a length of 30m and a width of 1.8m except Trench 7 which was halted after 7.5m due to collapsing ground at a depth of over 1.3m. Trenches 2 to 5 confirmed that the drift geology was a reddish-brown clay-with-flints that had been truncated during the construction of the Thames Water Pumping Station in the 20th Century. In trenches 1 and 6 layers of colluvium were identified, the upper layer of which contained an abraded Roman pottery sherd and a fragment of Roman tile. A trial sondage was sunk to 1.8m BGL in the east end of Trench 6 which revealed the thickness of the colluviums and that they were sealing a possible relict land surface of brick-earth. This surface showed evidence of burning and a light scatter of charcoal but the area was too small to make any further interpretations. In the 19th century the land parcel was still farmland and a terracotta land drain had cut the top of the colluvial layers providing a terminus post quem for this phase of the sites formation processes. Other post-medieval activity included a 4m-wide trench (or rectangular pit) in Trench 3 from which a sherd of whiteware was recovered but its function remains unknown. In summary, the sondage in Trench 6 had revealed a fall in the natural topography from the west of the site on the artificially created plateau (recorded at 59.37m OD) to the clay-with-flints natural at 53.08m OD to the east. The excavation proved that the steep slope eastwards into the Cray Valley was in fact natural and that a putative land surface survived along the south of the site beyond the area of truncation. |
