We presume you mean the Sierra Nevada ones (unless you're thinking of other Sierra's, which is just like saying mountains !). In Mann et al (99) in GRL they described a correction to the long bristlecone series to 'deal' with something odd in the series. This might be the same thing you're finding. So try Mike's paper and/or get in touch with Malcolm Hughes. A few days ago you sent me an extra diagram that you put together related to the Science paper. I have to prepare a conference proceedings paper for a meeting Tenerife on solar variability and climate in Sept. Can I use it with acknowledgement as an example of the EBM and the fit ? I gather from emails from Dietz that the conference will bring the discussion on solar/greenhouse forcing to a head. I'll be using some of your Science figures as well in the talk as I'll need some ammunition to defend your, mine and Mike's work ! Cheers Phil
