I fully concur with the comments of Peter Walker in his short summary for this hill, both in the directions given and as to the general whereabouts of the top. The highest point lies somewhere within the small 140m ring contour of fairly level ground broken only by a number of raised ditches. My best guess would be a point at J4806397115 E along the ditch running E off the road and along the S edge of a flat cultivated field . On inspection I found that the currently listed mv co-ordinates J481972 F lie within the bounds of this field but, if anything, at a point where the field starts to slope down E and not at the highest point. This said Donald's Carn is a non-descript hill with nothing to commend a visit unless,as in my case, to complete one of the outstanding hills in the new Local 100 list introduced by mv'v in January 2014. By the way a farmer who I met when I there was not aware of Donald's Carn as a name used locally. It may well be that it has some historical significance, now long forgotten.
