Cedar Lane Oak Cross-Section

Picked up the cross section of the Cedar Lane tree today that was prepped and dated by the Dendrochronology lab at Columbia's Lamont-Doherty Earth Observatory. Pretty cool, and currently taking up most of the back of my van. Interesting to see how different the size of a decade can be. This was cut from a spot that was probably 10-15 feet off the ground about half the base diameter. I counted ~180 to the hollow at the base. A wedge from the very base went to them as well, curious what the official dating will be, and the estimate for the ~2 foot hollow center. The outer corner of that post it points to about where I was born... Now to prep it for permanent display as soon as someone tells me where that's going to be.
