Some Wall at last

from reading rocks · host Ian Jackson

Send us Fan MailOur journey east continues, we are about one and a half kilometres north east of Lanercost just over the line dividing the red St Bees Sandstone bedrock from grey brown Carboniferous rocks – although there is no bedrock to see here – its covered by a variable thickness of glacial deposits. Those thick stony clays sand and gravels may well explain why the first incarnation of Hadrian’s Wall in the western sector was made of earth and turf and not stone. They also mean its essential to look at the building and wall stones to see get a feel for the bedrock. You could abandon the car and walk between the places in the 4 stories in this episode from Hare Hill to Appletree, Harrows Scar and Willowford Bridge. Its only around 8 km one way, pretty flat with great views and some brilliant archaeology including passing Birdoswald Fort. The dedicated Romanists and hikers amongst you could take in the Fort and the Roman inscriptions at Combcrag gorge on the way back - you’ll maybe remember that from Series 2.
