Trip report: High Country of the Eastern Sierra

ppine, that is interesting about the day length. But now I can't figure out why the trees change at different times from year to year?? Some years the third week in Sept., sometimes the first week in Oct. Should be the same date each year, I would think, but that is not what happens.

The other miracle is that the fall color is just a lucky accident -- the trees do not benefit from vivid coloration. This is unlike wildflowers, which use color as part of their campaign to attract bees and so forth.
