The sunlight highlights the steep-sided Greenholes Beck, where I more-or-less lived for five years in the 1990s, conducting PhD research by driving hundreds of 30cm long pins into rock faces, stamping around in thigh waders carrying 25 kg bags of cement and generally playing with mud every time (and I mean every time) rain fell; every one of the landslide scars is utterly familiar, even now.
Actually, it wasn't remotely as fun as that might sound, and I loathed every moment; the scenery was some compensation.

The Lune Valley and western edge of the Yorkshire Dales are in the background. The most obvious landmark I can identify is Barbon Manor, directly above the wind turbine on the left.
