"Shadows are so ephemeral and not 'scientific'. "

Oh I dunno, for every solar alignment there's a much more easily measured shadow, and an infinite series of them both before and after the moment of alignment so your options to tell the shadow-time all day or all year are vast. Bet some ancient people did so in some places.


"I also know that stone structures can appear to be unstable for years and then topple or fall"

Yes, the rate of progression can be jerky and unpredictable - climate, sub soil, vibration - it's very hard to be sure what is happening. There has been long term talk of driving a big road past the Rollrights. For a consultancy fee of £10K I'll state that the vibration could de-stabilise them. No-one will have the guts to state otherwise as no-one can know for sure. ;)
