Jon, haven't got a map ref for you - however, a clue appears in 'The Blitz Now and then' Vol 3 (p189) Ed. Winston Ramsey. Extract on the incident reads :

'December 17-18 Night : 2/KG2 Dornier Do217E-4 [4348]. Flew into hillside at RAVENSTONES, Wheeldale Moor, near Pickering, Yorks 10pm. Crew (listed) - all killed. Aircraft U5+AK disintegrated.'

Footnote reads : 'Owing to the remote nature of the crashsite, the wreck was not found for two days and many pieces were left in situ but these have mostly been removed in recent years.'

Hope the vague clue helps. Sugg check if 'Ravenstones' appears on OS map ? Good luck with hunt - be interested to hear what you dig up !
