Although there is only one barrow marked on o.s. maps I saw three in a mile long stretch of the valley , driving south. I managed to walk to the mapped one , it is on a footpath a short walk uphill.
The second one I managed to photograph from a passing place on the narrow road , unfortunately I was unable to take a picture of a third as it wasn’t safe to stop. I’m not sure about the trees planted on the first barrow , it is quite low and may well have been ploughed in the past , so at least the trees make that impossible at the moment.
