Three rescue teams were called out to aid an injured walker in the South Pennines.
Calder Valley Search and Rescue Team was asked to help Oldham Mountain Rescue Team with the incident near Summit.
Rossendale and Pendle MRT was also called to the site near Littleborough.
A Calder Valley SRT spokesperson said: “It often makes sense to mobilise neighbouring mountain rescue teams when the location of the casualty is so near the border of operational areas.”
The spokesperson said the attendance of three teams led to a rapid rescue of the injured woman and added: “Once on scene, the casualty was loaded on to the stretcher and safely transferred to the land ambulance for onward journey to hospital.”
The two-hour rescue involved 15 volunteer members of the Calder Valley team, along with colleagues from the two other teams plus a crew from the North West Ambulance Service.
