In 2006 and 2007, a 94km-long gas pipeline was excavated across the Pennines, from Pannal in North Yorkshire, to Nether Kellet in Lancashire (N/W England). Around twenty archaeological excavations were undertaken to mitigate the impact of the construction of the pipeline on the archaeology of the route, and these form the subject of this volume. The excavated remains were generally slight and were widely scattered along the route; the range of periods they represent is equally broad and intermittent. The earliest finds represented are Mesolithic flint scatters, with some evidence of Bronze Age activity, but very little evidence of settlement or land division, a pattern which broadly continues throughout the area's history.
