Evidence for the occurrence of a severe fire event in Great Basin National Park, NV during the late 15th century documented by Stephen Cooper was discussed at the meeting. Dr. Jiaying Wu presented a paper, co-authored with Sally Horn (University of Tennessee), on hydroclimate variability during the Terminal Classic Drought and the Medieval Climate Anomaly in the northern tropical Americas. Dr. Jiaying Wu published a paper describing multi-decadal to sub-centennial-scale hydroclimate variability in the glacial highlands in Chirripó National Park, Costa Rica.
