text: Thanks for the reply. Ive seen the Jacoby-dArrigo references and, in fact, thats what occasioned my interest. It was included in their northern treeline index which seemed a little odd to me, since the site is far from the treeline. I also notice that the earliest portion of the chronology (not used by Jacoby and dArrigo) is based only on one tree. If you were doing the chronology today, would you include the portion based on only one tree in your site chronology? Also do you know (from past notes or otherwise) any details about potential logging or other forestry operations in the area?
