Wolf lichen on a tree trunk near LeConte Lodge comes back to life with autumn Rains, Yosemite Valley.

If you read the “technical data” at the end of this post, you know that it was dark in this forest! The location is near the Le Conte Lodge (across the road from the Housekeeping Camp) along the south side of Yosemite Valley, and in an area where the tall cliffs approach very closely to the road and trail. Because of this it is deeply shaded for a good part of the day, especially during this time of the years.

I had gone here looking for maple leaves and for the large oaks that grow near the lodge. I just happened to see this interesting bark texture as I hiked past and noticed the brilliant – almost fluorescent – greens of the lichen in contrast to the dull color of the tree. While it was dark here and the shot required a long exposure, an upside was that the soft, diffused light lowered the contrast of the scene to manageable levels.

(I originally referred to “moss” in the title and description of this photo. Thanks to “Dave” for setting me straight and identifying it as fruticose lichen.)

Boulder and Tarn

A large boulder sits on a granite slab at the edge of a Sierra Nevada tarn whose surface reflects the sun-dappled rocks beyond.

A very short distance from one of the most popular viewpoints along Yosemite’s Tioga Pass Road I found a faint and unmarked trail heading off into a small valley filled with glacial boulders and a convoluted terrain of small hills, little tarns (seasonal meltwater pools), and forest. And, of course, tons of mosquitoes. Despite forgetting to apply the bug juice, the place seemed interesting enough that I persisted long enough to find and photograph this small, quiet tarn and the large boulder sitting a flat bit of granite along its shore.

Lodgepole Grove and Boulders – Lembert Dome

Lodgepole Grove and Boulders – Lembert Dome. Tuolumne Meadows, Yosemite National Park, California. June 5, 2010. © Copyright G Dan Mitchell – all rights reserved.

Glacial erratics and a grove of lodgepole trees along the lower slopes of Lembert Dome, Tuolumne Meadows, Yosemite National Park.

As I drove down into the Tuolumne Meadows area from Tioga Pass in the early evening I caught a brief glimpse of some interesting diffused light on boulders lying across the lower slopes of Lembert Dome and decided to stop. On a typical high-season summer evening this would be a very crowded place, but on this early June evening most people had left and I had it almost to myself.

By the time I parked and unloaded my gear and walked up this slope the light was not quite what I had seen from the car. The clouds to the west had thickened a bit and the glow that I had originally seen in the light was dissipating. I decided to stay to see if the light would come back, since I could see that the clouds might move enough to let the scene brighten a bit. In the end I didn’t get the light I had in mind, but I think this photograph may serve as a study that let me work out a few things I’ll do differently when I return to shoot this subject, perhaps later this summer.

Succulent Plant Growing on Rock

Succulent Plant Growing on Rock. Castle Rock State Park, California. April 24, 2010. © Copyright G Dan Mitchell – all rights reserved.

Black and white photograph of a single succulent plant growing on an almost barren rock face at Castle Rock State Park, California.

I wish I had a better title for this photograph, but I’m afraid that I am not expert at plant identification. (Yes, I’m hoping that someone who knows about these things will offer an identification – I’ll change the title to reflect this. Thanks in advance!)

(Update: “Thank you!” to Gena and Guy who suggest that it is a type of stonecrop. That makes sense to me.)

On this warm spring-like morning I hiked at Castle Rock State Park along the summit ridge of the Santa Cruz Mountains – this was my first hike of the season on which it actually felt like spring rather than winter. (It has been a wet winter here in the San Francisco Bay Area.) As I passed over a rocky section of the trail to Goat Rock I paused to think about photographing some ferns and wildflowers that were growing against the base of a small rock face. I didn’t find anything along those lines worth photographing, but I did spot this single specimen of some sort of small succulent plant growing out of seemingly nothing in the middle of the rock face. The plant’s location was so improbable that I stopped and looked around for another of the same type, but this seemed to be the only one.
