4. A magnified view of Red Oak 1 reveals closer detail of the limb and trunk junction in a Red Oak tree. You are looking downward in these views, at the end grain surfaces of the wood. A cavity caused by carpenter ants appears at the upper left. The size of these images have been kept small to accommodate a modest budget and older computer equipment. Computer memory requirements and processor speed are limiting factors in determining display size. Animations in this series are compiled from as many as 72 images in each.
