Hi,
Greetings from sunny Manchester (UK).
The photo is from one of my favourite crags called Stanage in the Peak District National Park.
The type of rock is officially known as Millstone Grit but known by climbers as gritstone or God's Own Rock or The Holy Grit.
The climbers are on Flying Buttress. The easier version goes up the left hand side and the harder one goes directly up over the big overhang.
