Autumn Foliage ObservationExtreme Foliage not only is at peak, but may be the best in years! The area right before the TH parking lot is so intense with every fall color, and the leaves and trees are healthy - leaves are not dry or muted! I went up both the Canyon trail until the last maple glen at the base of the rim and also the spur trail to the spring (which has a heavy flow!) Both trails are spectacular with a riot of color. If you only have time for one, the See Spring spur has almost constant color!
