"One of the small natural miracles in this part of the world is just an autumn rainstorm away. The first good rainstorm is the beginning of the salmon spawning season in Redwood Creek, a tiny stream that runs through Muir Woods National Monument." As part of Redwood Renewal at Muir Woods, the National Park Service (NPS) and its partners are helping undo the damage of the past and restore habitat for the federally endangered coho salmon.
