The stewards of Muir Woods endeavor to keep the park in a natural state as much as possible, and this includes usually leaving fallen trees and limbs in place rather than "cleaning them up". Here a large tree limb fell across Redwood Creek. The title of this image is shamelessly taken from a song by Simon and Garfunkel, but this water could hardly be considered "troubled" so I modified it accordingly.

This grand show is eternal. It is always sunrise somewhere; the dew is never all dried at once; a shower is forever falling; vapor ever rising. Eternal sunrise, eternal sunset, eternal dawn and gloaming, on seas and continents and islands, each in its turn, as the round earth rolls.
-- John Muir
