Reading history - one ring at a time
Kristen de Graauw balanced on a ladder as she pressed the school-powered borer above her into the dusty log that framed a Virginia barn's feed room for at least a century.
"I wanted something different and new and dendroarcheology sounded fun," said the Indiana State University graduate student during a break from boring samples from the wood. "This gives us the hands-on exposure of applying dendrochronology in different ways."
By attending the International North American Dendroecological Fieldweek, which was held in Virginia this year, de Graauw expanded her skills in the den of tree rings.
On this early August day in the barn, the smell of sawdust replaced the barn's age-old mustiness of hay and dust. The supplementary passing car competed with the hum of a generator and the whir of drills as de Graauw and eight other scientists bore dowel-sized cores of wood from the old logs. The barn's builders chose the sketch hewn logs, wider than a spread hand, to stand the test of time, and they have. But the question remains for the stylish owners of how much time they have withstood. The scientists, all students at NADEF, climbed inside stalls, in hay lofts and under the barn in an application to read its history.
