Summit Tunnel Air Shaft 4 and the Warland Valley

I took this picture in November 2013 with a Samsung Galaxy Tablet, I was out looking for the Summit Tunnel that runs underneath the Pennines Connecting West Yorkshire with Greater Manchester and eventually made my way up on to the hills above. The air shaft is number 4 and the Rochdale Canal and A6033 Rochdale Road can be seen in the valley bottom. www.colingreenphotography.co.uk
