They run underneath a skeletal metal tunnel with the massive redwood to the right. The tree is extremely tall but thin of leaves at its relatively skinny top. A tree that is about a third of its size stands to the right while a wooded are can be seen faintly in the background.; Picture file card reads "Oldest living landmark in California.
