A 24-year-old from Oxfordshire had to be rescued from the Pennines after collapsing with chest pain.
The woman, who was a member of a Duke of Edinburgh Award group, collapsed on Monday evening.
Rescuers found her at the top of Wildboar Grain, near Bleaklow Head, after the group had set off from Crowden for Hayfield.
She was treated at the scene by members of the Glossop and Kinder mountain rescue teams. Last night no further details were available.
