Stage 1: Use your OL28 1:25000 map
You are not at the Henlake Down trig point (it's a bit dull though the views aren't bad). You decide to start from Butterdon Hill trig instead. Following a stone row north you are lead to an abandoned tramway and stay on it until it forks; you take the right fork and follow it to the peak of the hill. A stone row runs over the hill so you follow it north for approximately 2.5km until it crosses another dismantled tramway. To the east there is a large cairn; you decide to climb it. Which OS grid square are you now in? Grid = ABCD
Stage 2: Visit the trig point and obtain the four digit number from the base plate. Trig No = EFGH
