I visited a few locations in the Mammoth-to-Bishop area today, and can add a bit of information to the general knowledge floating around on the net. I can’t speak about the whole Sierra, obviously, but some of what I saw today might give an indication of how things are evolving.
As a point of comparison, when I was in the area last week (the first weekend of October) the colors were tremendous at some of the popular, higher elevation areas around and a bit north of Bishop. In fact, the colors then were as good as I’ve ever seen. This was enhanced by the light rain and the overcast, both of which intensify the colors and reveal more subtle details.
Between then and now the Sierra had some serious early season snow and, at the lower elevations, rain. Partly due to this weather and partly to the normal progression of color, this week those higher areas have many leafless or nearly leafless trees – the colors there have pretty much run their course. The colors have moved down a bit in elevation, but have not yet caught up to what they were before. You can find good colors now, but you have to look a bit harder.
The good news is that there are a lot of very green trees in many of the middle and low elevation areas. This bodes well for the color prospects in the next couple of weeks.
I really prefer to photograph aspens in overcast conditions with subdued light. In fact, when it is clear I’ll often photograph the trees before the light is on them or wait until the evening and photograph them after the shadows from higher peaks move across the groves. This weekend, however, it is bright and sunny. On all counts except for aspen photography, it is beautiful weather! Today there were two somewhat special conditions. First, there is significant snow on the higher peak, and especially on the White Mountains across Owens Valley to the east. And this morning there was a fair amount of fog in the valley areas. In fact, this seemed so interesting that I chose to shoot these conditions out in Owens Valley this morning rather than chasing aspens!
