Two summits in the Northwest Highlands whose heights had been recorded as identical have been resurveyed. Buidhe Bheinn – above Kinloch Hourn – and Sgurr a’ Bhac Chaolais which overlooks Glen Shiel had both been measured by the Ordnance Survey to be 885 metres, but modern surveying equipment has been used to provide more accurate measurements. Previously both summits were collectively given twin Corbett status, but the new, more accurate measurements have found the more southerly of the two shown to be 29 centimetres higher than its neighbour.
Buidhe Bheinn was found to be 885.50 metres, compared to 885.21 metres for Sgurr a’ Bhac Chaolais. The Scottish Mountaineering Club (SMC) will now list Buidhe Bheinn as the Corbett, and Walkhighlands has amended its peak-bagging maps and records.
