NYSAA: Brita Lorentzen, Dendro and radiocarbon at Al-Aqsa

NYSAA: Brita Lorentzen (Cornell Tree-Ring Laboratory) presents “From the Forest to the Mosque: New Tree-Ring and 14C Evidence for Dating Jerusalem’s Al-Aqsa Mosque and Sourcing Its Timbers,”  6:30 pm Wed Oct. 2, 208 CNS Bldg, Ithaca College. Lorentzen uses dendrochronology (tree-ring dating) and modeling of sequences of 14C  dates (“wiggle-matching”) to obtain unprecedented dating precision for the al-Aqsa timbers and identify the forest area(s) from which these timbers were procured. Hosted by the New York State Archaeology Association (NYSAA, for more info, lwj1@cornell.edu.) Brita kindly gave a Cornell version of the talk Tues Oct 8 at 12:30 in the Dendro Lab.
