Even though the calendar reports that a few days of summer still remain, and the thermometer here in the San Francisco Bay Area still reads hot enough for summer, the annual autumn color show is now underway in the Sierra Nevada. I’m just back from four days “over there,” and I’d like to share a bit of what I saw, along with a few hunches about where things might go over the next few weeks. (Disclaimer: Predicting fall color is very much an inaccurate science — kind of like predicting the outcome of the playoff games before they begin. Over the years I’ve been surprised many times, and we really won’t know how this year’s color plays out until it happens.)

Between September 16 and 19 I visited the Yosemite around Tuolumne Meadows, a few spots well east of the Sierra with views back toward the range, the Mono Basin, US 395 between Conway Summit (just north of Mono Lake) and Bishop Canyon, and Bishop Canyon itself.

Acknowledging the risk of pronouncing this to be an “Early Aspen Season This Year!”, I’m going out on a limb and saying that it did seem like some of the color is progressing on an early than usual schedule. I usually wouldn’t both seriously hunting for aspen color in the Sierra this early, but I found a number of places with color worthy of photographing. In fact, I had the joy of photographing alone in some locations that will be overrun by photographers in a few weeks! (To be clear, and as I’ll clarify below, there are still lots of very green trees!)

For example, the photograph above was made up in Bishop Canyon at between 8000′ and 9000′ in a place that I visit every year. While these particular trees are often among the earliest in the area to change colors, seeing almost an entire slope of yellow/gold this soon is not what I would expect.

Most of the early color comes from small aspens, growing at relatively higher elevations, and often on what seems to be margins terrain — in very rocky areas, along talus slopes, and it areas that are typically dry. There is some extensive color in some areas east of the Sierra, areas that are drier and tend to support the smaller “scrub” aspen trees.

Would I recommend going up there right now to see the color? Not exactly, though if you do go you’ll be able to find some nice color if you poke around a bit in the usual places, emphasizing the higher and rockier locations. That said, there are still a lot of very green trees, and the vast majority of the bigger and taller trees are essentially still completely green. This is especially true in the low elevation canyons, where the trees often grow larger and are sheltered more from the elements.

When will the rest of the trees change? Good question! I don’t know, but I have some hunches. Typically they would get their color after the start of October, and some years ago I would look for the best color beginning a few days into October and continuing through the second week and possibly a bit later as the final good color comes to large, low elevation aspens. My thinking this year is that last year’s (2015) pattern may be a guide to this year as well. Color last year also started a bit early. Last year it also looked like some trees were stressed by the prolonged drought. But in 2015 many of the bigger trees in areas perhaps less affected by drought seemed to change on almost their typical previous schedule. This meant that at any given moment it might have been a bit harder to find the “perfect grove,” but that the season actually lasted longer due to the early start.

Speaking for myself, if I had a choice between going early in the usual time frame (starting near the beginning of October) and going later (say at the end of the second week of the month) I would be more inclined to gamble on the early time rather than the later this year. In round numbers, perhaps aiming of the first week of October would be a good bet — though I’m also confident that, barring weather surprises, there will still be color at lower elevations and among the largest trees later on, too.

Happy aspen hunting!
