Calf Top (SD 664 856) is a rather unassuming hill which is approximately 6km south of Sedbergh in the Yorkshire Dales. It rises above the deep cleft of Barbondale to its east and Dentdale to its north, and although not the highest hill in the area it is quite prominent above its surroundings.
However, it isn’t the hill’s prominence that is of interest, it is its height, and being a mountain surveyor those hills that are given a 609m spot height on Ordnance Survey maps are particularly interesting, as this height equates to just under 2,000ft, with 609.6m the metric equivalent of this all important imperial height. All important, as 2,000ft is generally regarded as the benchmark height in England and in Wales for when a hill is promoted to the dizzying ranks of a mountain.
