There's a clearing by the creekbed and, likewise, all the way up the vertical expanse of the towering redwoods. This clearing allows the sun, passing overhead, to cast its light and temporary warmth on the mossy surroundings. This otherwise dark laboratory of algae gets a lightshow on a daily basis, the kind where individual rays of the sun get amplified, as if taking turns or working in tandem with one another. A stage really, acting out the whimsy of nature as she shows off her colors, her variety, and her splender of ongoing, never ending activity.
Otherwise dark, dull greens come alive to reveal multitudes of shades and hues when exposed to and highlighted by the sun. The trees play a part as they filter this light at various angles through their branches. The damp air itself might stir enough to mix in dust particles, now seeming to float in the stew of yellowish sunbeams.
Observed or not, this play goes on everyday, as if for Nature's own pleasure; an expression of herself which requires nothing.
