The brilliant picture above comes to us from Twitter where it was posted by a kind copper in the Metropolitan Police Helicopter service. It is an irresistible shot that echoes the fact that the Ladder is technically visible from space when lit. The railway is along the top of the Ladder with north to our right where the lights of Turnpike Lane bus and tube complex can be seen. The dark area extending from that towards the left and shortening five of the roads is Ducketts Common. And I could mark my house with an X - its at this end of the first full length road from the right!
I am hugely indebted for this picture to Hugh at Harringay On Line who put it together. In this form it isn't too easy to see but worth the effort. The under picture is a Google Earth view of the Ladder with the railway sidings at the top and Turnpike Lane station at bottom right. Overlaid is an ancient map of the old Hornsey House estate on which the entire development was built.
