Track: Climate of recent millennia
We present two reconstructions of annual average temperature over temperate North America: a tree-ring based reconstruction at decadal resolution (1200–1980 CE) and a pollen-based reconstruction at 30-year resolution that extends back to 480 CE. The tree-ring based reconstruction was calibrated against instrumental temperatures, was then reduced to a lower resolution and used as a calibration t ... More

We developed earlywood and latewood chronologies of frost-damaged rings (frost rings) from three lower forest border Douglas fir (Pseudotsuga menzeisii Mirb. Franco) sites in central Idaho, USA spanning AD 1281-2009. In these records, frost rings occur more frequently in earlywood than in latewood, tree age does not significantly affect whether or not a tree records a frost event, and some weak tr ... More

High elevation tree-ring widths from Great Basin bristlecone pine (Pinus longaeva) are a particularly useful proxy to infer temperatures prior to the instrumental record in that the tree-rings are annually dated and extend for millennia. We have created a very long (4500+ years) annually resolved record of ring width, and an estimate of past treeline elevation for the Great Basin, USA. These recor ... More

Track: Climate of recent millennia
Turquoise, parrots, and other goods appear to have been exchanged between the ancient Southwest and central Mexico during the Classic and Post-Classic Eras. Exchange along the ‘Turquoise Road’ brought at least some Mesoamerican ideas into the Southwest, notably at Casas Grandes, Chihuahua (Paquime), and Chaco Canyon, New Mexico. Major questions remain about the importance, timing, and climat ... More
