Willow Valley in the South Fork Bishop Creek area is in decline. With a long lens you can still pick out color but most of the areas in Bishop Creek have lost over 50 percent of their leaves. This photo was made on October 22, 2011 with a Canon 5D MkII camera using the Canon 24-105mmL zoom set to 55mm. The exposure was 1/90 sec. at f/11 using ISO 400 and a Polarizing filter.
