Frozen Peat on Birks Fell
|Elevation||610 m (2,000 ft)|
|Parent range||Southern Yorkshire Dales|
Birks Fell is a hill in the Yorkshire Dales, near to Hubberholme in North Yorkshire, England. It is classed as a Marilyn (a hill with topographic prominence of at least 150m). Birks Fell only became an official Marilyn in 2006 as it was resurveyed and discovered to be 610 metres (2,001 ft) and not 608 metres (1,995 ft) as previously thought. Books from the late 19th and early 20th centuries list the hill as being 2,001 feet (610 m) and it is thought that in the conversion to metric, the hill lost some height. This raises it above neighbouring Horse Head Moor (609 m), making it the Marilyn in place of Horse Head Moor.
Between the summit and a trig point (1 mile (1.6 km) to the south west) lies Birks Tarn, which is one or the largest tarns in the Yorkshire Dales. It is prevented form leaking through the bedrock underneath by its impermeable layers and additionally held back by the peaty soil. The section at the top of the fell is a wide ridge that offers excellent walking and "outstanding views".
