On Friday afternoon mountain rescue was contacted by police following reports that a walker had fallen unconscious.
The team was mobilised around 1pm after the call from police.
Volunteers from the Rossendale and Pendle Mountain Rescue team were able to reach the walkers as they were retracing their steps from Ogden Clough down towards the reservoir.
The walker was brought down from the hill to Barely and an Ambulance was waiting for them.
A spokesperson for the mountain rescue team said: “The callout was at lunch time on Friday, shortly after 1pm, to assist a walker who had become unconscious whilst walking up Pendle hill.
“Their location was initially unclear from the information through Lancashire police, but as the team was mobilised we were able to speak directly to the informant and confirm they were slowly retracing steps from Ogden Clough, and descending back to the reservoir.
“As team members arrived at the upper reservoir, local police had been able meet to with the walking group, who had made slow but steady progress to self-extract off the hill.
“The police were conveying the casualty down to Barley to meet with an ambulance for further assessment.”
