Photo of digitizing core w-slider ring.JPG: An increment core is cradled in a shallow groove of a wood block on a sliding stage, which allows the core to move along under the view of a microscope. The microscope is wired into a computer that crossdates and digitizes the core as it moves from one section to the next.
