we noticed you have removed the Toothill site - although you've made reference to a longbarrow you have discovered in Bolton in a few forum posts. is this because you no longer consider it to be a valid site? after visiting it again, it does seem pretty unlikely.
you have referred to a bronze age burial mound nearby. is that the mound in the back garden of the stone cottage at the end of harvey street? that at least seems possible though it's difficult to tell without access - what makes you think it is?
