The Cornell Tree-Ring Laboratory New York State and NE North American Dendrochronology Project is working to date historic buildings and build tree ring chronologies as far back in time as possible for Northeastern North America. The project is under the direction of Dr. Carol Griggs. We are interested in all wood from the present back to the late Pleistocene, this ranges from historic houses and buildings and structures in New York and Northeast North America to old to very old wood from excavations, ponds, lakes, road cuttings, etc. More information about the New York State and NE American Dendrochronolgy Project is available here: https://dendro.cornell.edu/.
