At the tor, you continue uphill to the highest point, gaining approximately 150m in altitude. From this point, you continue due east for 2.5km where you encounter a small brook. You follow the brook downstream until you see the remains of a tinner's hut. Which OS grid square are you now in? Grid = ABCD
