2022 Fall Color

It is that time of year again — my favorite season! This past week on walks here in the San Francisco Bay Are I have noticed the signs of the seasonal change. The sun is setting an hour earlier, our first (early!) Pacific weather front is arriving this weekend, some trees are starting to change colors, and the sound of old leaves skittering along the ground in the breeze is everywhere.

Fall color is more prevalent here in California than many realize. The earliest hints come to the high country of the Sierra Nevada in late August, when something in the air changes, corn lily plants turn yellow, the bilberry starts to pick up a bit of red, and you might even find an odd yellow aspen leaf here and there. Things pick up as we progress through September, and by the very end of the month it is often possible to start finding a few examples of good aspen color up high. Then the color works its way down to lower country, the valleys, and the coast over the following months. I’ve sometimes photographed “fall color” in the Central Valley as late as… January!

The main aspen color season in the Sierra peaks during the first half of October. It tends to start at higher elevations as early as the very end of September, becoming quite pronounced early in October, and working down to lower elevations into the third week of the month. If you can only go once, targeting your visit for about one week into the month is a good plan.

No one knows for sure how the season will evolve. Some things stay relatively constant from year to year, while others vary quite a bit based on temperature fluctuations, the amount of precipitation that fell during the year, whether or not early storms sweep through, and more.

I share annual updates on my Sierra Nevada Fall Color page at this website. I just posted this years first message there today — it is mostly some early thinking about how the season may evolve, along with a record of what has happened in some previous seasons. The latter may be useful as you plan your autumn color search in California.

One more thing: I may have something new to write about regarding fall color in a few weeks. Stay tuned…

Tall aspen trees begin to take on fall colors, Eastern Sierra Nevada.

Previously I shared a different view of this grove of aspens. (More on that below.) It is part of a large grove in the Eastern Sierra that is easily accessible. As a matter of fact, I photographed it from a spot just a few feet off of a roadway. Here a large expanse of trees rises from the bottom of a valley, working its way up talus slopes toward higher peaks. Because virtually the entire grove is open to view and spread out before me, I often use a long lens to pick out small compositions from within the larger totality. This photograph focuses on a group of tall, thick, mature trees.

About that “different view” that I mentioned above — the previous version was in portrait (vertical) format while this one is obviously presented in landscape view. If you imagine that there is one “best” way to depict a subject, the choice to share both might suggest a lack of clarity on the part of the photographer. Obviously, I feel differently. I do not think there is one right or even best way to frame or format a subject, and I believe that there are multiple ways to look at it. Beyond that there is a practical value to seeing such a subject in more than one way, as anyone who has worked with photography clients understands. In the end, I actually like both ways of seeing this grove.

Early Aspen Color

Early autumn season aspens begin to change color.

As fall approaches I always anticipate the color change of aspen trees way in advance of the actual event, and I start watching for early signs more than a month before the color peaks. Way back in August I typically find a few early clues — yellowing corn lilies, drying meadows — and at some point in September I find my first few yellow aspen leaves. The change begins in earnest by the first week of October, and that is when I made this photograph. At this point, the aspen trees seem to move toward a sort of “lime green” color, often with a few interspersed yellow leaves, and in the right light you can convince yourself the fall colors have arrived.

There is a useful lesson about lighting in this photograph, too. Although this scene seems pretty straightforward, there’s more going on with the direction and color of the light than you might first notice. This grove of trees is, indeed, in the shade. The camera is pointing roughly east, a tall ridge rises behind this little grove, and it was still shading the trees hours after sunrise. This provides soft light that fills in shadow details much better than direct sunlight. Look deeper into the grove and beyond and you may notice that the color becomes more blue. Light in shadows is usually quite blue — after all, the main light source is the very blue sky! But the trees in the foreground are not very blue… and there’s a reason. Behind my camera position (if we could turn around and look backwards) was a very large mountain in direct sunlight, and the reflection of that light was strongly diffused and directed straight into the grove, warming the colors and highlighting the front trees.

Sierra Fall Color Update (9/20/16)

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!
