Well nobody has disputed the antiquity of these sites. The county archaeologist thought one stone row was the remains of a medieval field system, even though he found a cupandring stone among it. Then he listed the site under the wrong name. But, no, none of them are disputed, they're just ignored. It's as though there were an exclusion zone around them. I could draw the boundaries of it - the Cumbrian border from Talkin to Melmerby. Melmerby to Allenheads. Allenheads to Haltwhistle. Haltwhistle to Talkin. There are exceptions, of course, but only just one or two.
