Did you know that tree fir needs follow a harmonious pattern on the water surface of a slow moving creek or river.
The wind that gently blows across the surface of the water tends to control the pattern of how each fir need lines up (with each other nearby fir needle) by effecting the lighter higher stem end of the needle.
The heavier dark root base of the fir needle sinks slightly below the surface of the water and is controlled by the gently flowing creek water current.
Thus each fir need tends to line up and follow the one before it - all in a slowly curling orderly procession of fir needles, each following its lil' bro' across the water surface, guided by the movement of water and by the gentle touch of a slight breeze disturbing the water surface - kind of like a series of boxcars on a railroad train - or like a string of pearls.
