15B Beinn Tharsuinn N
From Glencalvie Lodge car park I headed S, skirting round the Lodge boundary fence, to follow the road alongside the Water of Glencalvie. The path on the map, from just before where the road croses the river, was not easy to follow and in many places not visible on the ground (it might have been easier to follow the Allt na Crannaich to Dunach Liath). It was easy going along the ridge to Dunan Liath (Sim) and Carn Feur-lochain (Hump) then turning SE then S to Beinn Tharsuinn and descending ENE before climbing Leaba Bhruic (Hump) and the Diebdale Ridge. I descended mostly on a track to Diebdale and the forest road back to the car.
