15 Now we are on the wet route (at a dry bit) looking back from whence we have come. Where the dyke appears to swing to the left in this picture is actually where we came down from the wee valley. The main dyke heads straight on through the trees beyond that back to Screel. We stay with this main dyke for a short distance till it meets another one at right angles. You turn left there and follow that dyke up the hill.
