The route goes straight up the short wall and directly up the wall above, The top may be overgrown now.
****The latest BMC Froggatt area guide incorrectly describes Non-stop Nightmare as climbing the dirty corner and Scoop-a-poop climbs the wall to left. In fact the latter is just a direct finish to Non-stop Nightmare. All previous guides describe Non-stop Nightmare as climbing the wall left of the corner and this was done in 1978****
