It's a long link but you should read this - badly written - article ( http://www.davidaspinall.co.uk/disperse/Smithills%20Ancient%20Monuments%20-%20revised.pdf ). Post photographs to the nearest listed site with a tag something like 'this is two miles to the west'. There's a lot of stuff just out of Barrow Bridge. My latest find is an opened small cairn - say three hundred yards from the top of Sixtythree Steps.
