olo. From the car park at the top of the Glen Ogle pass. Started walking on a track, not shown on my map, to a mast. At one point there had been a somewhat newer track constructed to replace an earlier one. The mast is not shown on the map either - it lies on a minor bump a little west of the summit of Meall Buidhe. I continued with no track or path to the summit of Meall Buidhe. Returned more or less the same way. Weather good. The map used was OS 1:50,000, sheet 51, Edition B revised 1998 with selected changes 2002, 2007 B2.
