I am again recommending the Chacoan website created by Teofilo – Gambler’s House (an allusion to the Navajo history of Chaco). He writes well and thoughtfully, interspersing interesting photos in the text. In particular, Teofilo sums up the information about the source of all of the wood used in Chaco in this entry:

Where They Got the Wood « Gambler’s House

I’m certain it is not for lack of knowledge that he doesn’t mention that some think Chimney Rock was an outpost for gathering wood that might have been floated as far as Chaco. I don’t know if there is any merit to this idea. However, waterways may explain why wood would come from some areas and not others. In particular, Jemez may not be upstream from Chaco. peace, mjh

Update 7/9/09: Asked and answered. In his next post, Teofilo destroys the floating logs hypothesis, which I think I heard at Chimney Rock — and clearly, the eponymous rocks are all the reason the Chacoans needed to be there. Nothing like the careful consideration of facts to undermine a lovely idea. Still, in all matters, remember that the word facts often should be followed by “as we know them now.” Not said to undermine Teofilo’s facts — he has quite a grasp.
