Great Dun Fell, Cumbria (10. Summit of Knock Fell)

In 1884, Reverend Joseph Brunskill read a paper on ‘The Helm Wind’ at a meeting of the Royal Meteorological Society. Like those before him, he also drew attention to the noise: a distinctive roar giving warning of the imminent winds. Following this, the Society put a letter in the local Penrith newspapers asking for people’s records and observations of the Helm Wind. From the responses, 93 instances of the Helm were identified between 1871 and 1884. William Marriott, Assistant Secretary of the Royal Meteorological Society, also visited the area. He wrote: “We were frequently told that haystacks were sometimes overturned, men on horseback blown out of the saddle, and other damage done by the wind.” Directions to stop 11 Continue along the Pennine Way for about 1 kilometre slightly downhill, across patchy moorland vegetation. There is a flagstone walkway to follow in places. If the weather is clear you are walking in almost a direct line towards the radar station. Stop when you reach a tarmac road and signpost.
