I’ve just returned from my first trip of the season to photograph Sierra Nevada fall color, and I have a few impressions and observations to share.

In a typical year the peak of the Sierra Nevada aspen color generally occurs around the first two to three weeks of October, so I would not usually head up there to photograph the fall color in September. But this is not a typical year. After four years of historic drought conditions in the Sierra, the normal seasonal cycles seem to have been disrupted. With that in mind I felt it might be worthwhile to go a bit early this year, and my visit was rewarded with some excellent early color.

Some Speculation

Every season brings reports that “the color is coming early this year!” Eventually I figured out that this is quite often a matter of folks becoming overly exuberant when they see the first early signs of the color change, and that things tend to play out on roughly the same schedule almost every year. There are variations, but they are most often rather small.

This year I’m prepared to go (a little ways) out on a limb and say that things do seem to be different this time, though I’m a bit cautious about overdoing the extent of the difference. The photograph at the beginning of this article embodies features of the pattern that I believe I am seeing. Notice some trees without any leaves at all, some trees that already have intense color, and some trees that are still quite green.

Here is my sense of what is going on. Note that this is essentially personal speculation and guesswork based on what I see, and that I can’t guarantee that I’m right or that things will play out as I imagine they might. That said, I’m planning my own eastern Sierra aspen hunting around these assumptions until I see evidence to the contrary.  Continue reading Sierra Fall Color — Late September 2015 →
