Directly out of Great Missenden, walking up Frith Hill, the footpath eventually levels out and you arrive at a patch of woodland which covers some old earthworks. This is where HS2 emerges form the Chiltern Tunnel into a cutting on its route north. To 'protect' the earthworks and woodland, the small farm track around edge of the woodland marks the edge of the excavations for HS2.
The image above looks northwest down what will be the cutting. The panorama below looks across what will become the tunnel portal.
A soundscape from the edge of the woods in this location is available in the Last Chance (HS)To Hear blog.

The top of this hill is flat, which doesn't give a very good view; and the view isn't enhanced by the pylons anyway. What makes this location valued is its relative transquility, isolated by elevation from the road and urban noise. The woodland and its fringe is alive not only with birds, but with the hum of insects. That's an ever rarer thing in the south east generally, and that's the one thing that the tunnel portal development will definitely take, irrespective of efforts taken to landscape the scene and to protect the woodland and the earthworks.
