Digital Data from an Evaluation at the site of the A355 Beaconsfield Eastern Relief Road, 2017

This collection comprises reports, images, spreadsheets, CAD, and site records from evaluation at the site of the A355 Beaconsfield Eastern Relief Road undertaken by Oxford Archaeology (South) in 2017. A total of fifty four trenches 25m long and 1.9m wide were excavated, according to the layout in the Written Scheme of Investigations approved by P Markham of BCC. Seventeen of the trenches proved to be devoid of archaeology. The ring ditch suggested by the geophysical survey was investigated by Trench 10, but proved to be a large pit of late postmedieval date. One flint knife was recovered from a gully in Trench 3 and another from a pit in Trench 25. Archaeological features were more distinct, and more numerous, in the central and southern part of the site, and here concentrations of struck flints and Roman pottery were found.

本数据集包含2017年由牛津考古（南部分队，Oxford Archaeology (South)）开展的A355比肯斯菲尔德东部纾缓道路（A355 Beaconsfield Eastern Relief Road）现场评估所产生的报告、影像资料、电子表格、计算机辅助设计（CAD）文件及遗址记录。根据白金汉郡议会（BCC）P·马卡姆（P Markham）批准的《书面调查方案（Written Scheme of Investigations）》规划，共开挖54条长25米、宽1.9米的探沟，其中17条探沟未发现任何考古遗存。物探（geophysical survey）所推测存在的环形沟，经10号探沟发掘验证，实为一处后中世纪晚期的大型坑穴。3号探沟的一处冲沟中出土1件燧石刀，25号探沟的一处坑穴内亦出土1件同类器物。遗址中部与南部区域的考古遗迹更为清晰、数量也更为丰富，此处还发现了打制燧石与罗马陶器的集中分布区。
