Mist and Curving Ridge, Yosemite Valley

Mist from an autumn storm flows across the crest of a curving ridge high on the walls of Yosemite Valley.

The mist from this late-October storm is flowing over the edge of a curving ridge high above the floor of Yosemite Valley, leaving just a hint of the higher, curving ridge above this pinnacle through the clouds at upper left. This photograph, like one I posted very recently, was made as I alternated my attention between the image of Upper Yosemite Fall alternately transitioning between filtered sun and obscuring clouds and small details of the closer Valley walls as seen in this image. From moment to moment there were many interesting combinations of light, cloud, trees, and rock… but they came and went quickly and almost without warning.

I usually post photographs here before printing them, and not all of the posted photographs necessarily get printed. This one is an exception in that I made the first print of it yesterday. I’m also happy to say that some very subtle details that are barely or not visible in this web jpg reproduction are there in the print, including some faint outlines of trees in the upper left portion of the frame and some details of the rocky face at lower right.

Sand Patterns, Death Valley Dunes

Linear and curved patterns in morning light at Death Valley Dunes, Death Valley National Park, California.

Early in the morning on the third day of my late March trip to Death Valley I wandered out to Death Valley Dunes near Stovepipe Wells, taking the easier route around the west end of the dunes and then walking toward the higher dunes and shooting more or less towards the rising sun. There are plenty of interesting subjects when approaching the dunes from this direction: the patterned mud (or so they seem) formations beneath the edge of the dunes, the many small plants coming up after recent rains, flowers everywhere, the taller dunes to the east catching the first light, and beyond them the darker peaks of the Amargosa Range.

After climbing to the top of a moderate size dune to get a better and more open view to the east I happened to look down and see this steep, sandy slope with its linear pattern apparently created as sand blew over the edge and down the side. Beyond are the more typical gentle and curving slopes – here with some footprints from the many people who had earlier wandered through this section of the dunes.

(I think that we are seeing more people walking out to the dunes now that the NPS has created a actual “official” parking lot with marked spaces, rest rooms, and interpretive signs – an update from the old practice of simply pulling off the side of the road.)

Winter arrives in the Sierra?

A few years ago I did what was a traditional end-of-season backpack trip out of Tuolumne Meadows on the last weekend during which the NPS permits overnight parking on Tioga Pass road – this is typically on or just before October 15. It was a beautiful weekend with – as I always hope for in October – pleasant, sunny conditions and beautiful light.

The following weekend a backpacking buddy who had been unable to make that trip tried his own end-of-seasons visit, hoping to wander up into the Twenty Lakes Basin area just east of Tioga Pass. He arrived late and rolled out his bivy sack at the small campground by the lake right below Tioga Pass… and woke up the next morning with more than a half foot of snow on top of him and more on the way. He scrambled out of his bag, got into his car, and managed to get out just before the road was blocked. He liked to say that he was there for the switch from fall to winter… literally.

It sounds like something similar may happen over the next 24 hours. From all reports, one of the biggest October storms that we’ve seen in California in decades may be sweeping through tonight and tomorrow, bringing heavy winds, a lot of rain, and the potential for some significant snow at the higher elevations.

The folks at the Dweeb Report (interesting source of Sierra weather info) include an ominous sentence in their most recent update: “WINDS WITH THIS SYSTEM OVER THE CREST COULD REACH BETWEEN 120MPH AND 140MPH OVER THE CENTRAL SIERRA.”

Of course, you knew this was leading to a comment on aspens, right? Given the rather strange conditions for aspen color this fall, somehow it doesn’t seem at all surprising that the storm might bring down a good portion of the remaining leaves!

Bishop Aspen Creek Conditions – 10/3/09

(Since posting this message I posted a later update on conditions during this period: “More Eastern Sierra Aspen Color Conditions“.)

I’m currently down in Bishop “doing email” at Starbucks for an hour or so during the harsh light time of the day, so I though I’d post a quick report on conditions in the Bishop Creek area today – along with some (semi-) educated guesses about what lies ahead.

I was up way before dawn this morning and heading up 168 well before the sun came up – there was a bit of light in the sky. My plan was to do “the aspen thing” very early, but as I drove I saw that the clouds were likely to light up in interesting fashion and that it looked like there was some light precipitation on the highest peaks that would soon be illuminated by the sun. So I took a detour out into the Buttermilks on Starlite Road, found a spot looking at Mt. Emerson (?), set up my shot, and waited. I figured that an almost sure thing here was worth a slightly later arrival at the aspens.

The clouds and the wind suggested that the weather forecast of, uh, clouds and wind was probably accurate… I soon finished shooting here and headed up 168. The wind strengthened, at some points blowing hard enough to raise dust clouds on the surrounding slopes. After passing through Aspendell, where the trees are still completely green, I began to see some color just above here. I’d say that it more or less begins above the Cardinal Resort, though the real color starts a bit higher.

I decided more or less spontaneously to try North Lake. I had heard that the “river of color” above the lake had mostly passed its prime and was partially brown, and I knew that the wind would interfere with photographs of the lake, but I also figured that some close-up photographs of sheltered trees might work. There was a fair amount of color along the first part of this road – I came back later and spent some time shooting there as the sun/shadow line approached – and again after the exposed section overlooking Aspendell. Clearly the trees that were further along in the color transitions have taken a bit of a beating from the wind, though there are still quite a few green trees and enough color among the others to make the trip worthwhile. (I also like shooting bare or nearly bare aspen trunks…)

I drove up toward Sabrina but did not stay, instead deciding that the road to South Lake might be more promising. I returned through Aspendell an then turned right to head toward South Lake. The trees before the small village a ways up the road are almost all completely green. Above this village some color starts, and eventually there were some very nice sections. While the conditions ranged from green to yellow to “leaves all gone” and included some brown leaves, there were still plenty of shooting opportunities. I eventually ran out of “good light” as the morning wore on, but I’ll likely had back up that way this afternoon and evening since I located several promising locations.

My general sense of the conditions is that they are a bit unusual. It seems to me that the elevation where the trees start to change color is a bit higher still than I would have expected – it surprised me a bit to see no color at Aspendell, for example. On the other hand, the color started fairly quickly above this level as I ascended. Yes, there are some brown leaves (though these, too, can be interesting photographic subjects) and yes, the wind is blowing down a lot of leaves. But even up high and close to the areas where the leaves have blown down I could find other sheltered groves with excellent color.

So, what now? The weather report still calls for much colder conditions tonight along with the possibility of snow flurries. I think that the aspen conditions in the higher areas are likely to deteriorate somewhat quickly if this holds. On the other hand, there is still a lot of green! The middle and lower elevations have largely not changed yet. Perhaps the change to colder conditions will trigger a change there – and those who are coming up in the next week will find great color.

On another topic: For the past few years Vern Clevenger has had a gallery a couple doors down from the Bishop Starbucks. This morning I saw that Vern is no longer there. I just checked his web site and see that his gallery has moved to Mammoth at 220 Sierra Manor Road #4. I guess that Bishop’s loss is Mammoth’s gain!
