November 2016: On November 28, 2016, the resort towns of Gatlinburg and Pigeon Forge were ravaged by a wildfire that raced from Chimney Top in Great Smoky Mountains National Park down to the cities at the base of the mountains. This would begin a long series of news stories about my prediction that Gatlinburg would one day go up in flames.
December 2016: Henri travels to Concord, New Hampshire to begin a rather cool project that involves dating the year of death for a branch that fell off a tulip poplar tree and injured a passing citizen beneath the tree. And he was successful! The branch died in 2006, many years prior to it detaching from high up the tree and injuring that person!

July 2017: Maegen and Henri spend a 4th and final summer finishing up the collection of core and cross section samples at her study site in the Beartooth Mountains of northwestern Wyoming for her dissertation research. I don't think we're done yet, though! We already have done scouting for additional future projects!
July 2017: I knew this day would come! I've participated in a mind-blowing 20 North American Dendroecological Fieldweek (NADEF) events, dating back to 1991. Sadly, this year's NADEF was my last, as it is time now that I spend my summers wrapping up publications and manuscripts that are long overdue.
August 2017: We welcome a new graduate student into our tree-ring lab family! Laura Smith joins us after completing her masters degree at Frostburg State University in Maryland where she concentrated on ethnobotany and dendrochronology, She comes to us already with a wealth of knowledge in the tree-ring sciences. Welcome, Laura!
