This is the basal disk from a Redcedar tree that was in competition with a neighboring White Ash. The annual growth rings show that the Redcedar grew well for about 45 years, and then slowed dramatically when the White Ash overtopped it. Markings on the disk record the sizes of roots heading toward neighboring trees and saplings of varied sizes. The heartwood calls to mind an angel, surrounded by a lighter nimbus of sapwood.
