Natural Arch, Sierra Nevada

August 19, 2010 G Dan Mitchell Leave a comment

One of two known natural arches in this area stands high on a ridge.

Although I have visited this area for decades and know it quite well, this year was the first time I had taken notice of and actually visited this natural arch or bridge, supposedly one of two in this region. (The other is, from what I’ve heard, underwater!) I won’t say too much more about this feature since it seems to be pleasantly unburdened by tremendous waves of tourists at this point… If you know where it is, I urge you to do the same.

(To illustrate how important this is with a fragile feature such as this arch, after I posted this image somewhere else a person followed up with a photograph of some damned fool standing on the arch! This demonstrates a gross disregard for this beautiful feature – there are weaknesses in the rock at the ends of the arch, and taking risks with a feature like this one that took nature thousands of years to construct is the height of irresponsibility.)

Point Lobos Rock Patterns #1 – July 10, 2010

July 25, 2010 G Dan Mitchell 4 Comments

Black and white photograph of abstract rock patterns near Weston Beach at Point Lobos State Reserve.

This detail of the Point Lobos shoreline rocks was also photographed in an area just a bit north of Weston Cove where large rocks are lifted up at striking angles and the surf has worn away successive layers of sedimentary rock to reveal wild patterns. Some of the colors in this bit of rock were quite intense – the rock on the left is intensely reddish-brown in the original capture – and seemed to overwhelm the subtle patterns, especially those on the right side of the image.

I don’t know if it is apparent but this is a highly post-processed image. I don’t think it is necessary to spoil the fun by going into all of the gory details, but this image depends quite a bit on work in post.

Point Lobos Rock Patterns #2 – July 10, 2010

Detail of patterns in eroded shoreline rocks, Point Lobos State Reserve.

Another photograph of eroded rock patterns near the water not far from Weston Cove at Point Lobos. Here the top layer of reddish rock has worn away in places, leaving a much lighter layer of what I guess is some kind of sandstone below. I’m no geologist, but this section of seashore has fascinating rock formations on the small and large scale where many strata have been exposed by the surf. In some places there a big gobs of conglomerate rock, composed of many smaller rocks “glued” together. In other places very thin layers lie one on top of the other and they have been partially uncovered and worn away by the surf, creating amazing patterns.

Volcanic Ridge, First Light

July 7, 2010 G Dan Mitchell 2 Comments

Dawn light illuminates the Jeffrey pine covered ridge of a volcanic dome in the Mono Craters complex, California.

I have a favorite personal spot where I often stop on my way to photograph at South Tufa at Mono Lake. It is spot that you would likely pass right by since, save for a bit of a panoramic view, there is nothing immediately impressive about it, and because you would probably be on your way to someplace else, namely the formations at South Tufa.

On this late June morning I took a break from photographing in the Tuolumne/Tioga Pass area to shoot a bit around Mono Lake, where I had it in mind to shoot certain high desert subjects that I’ve worked on in the past. As I shot those other subjects I’ve often looked up at this particular ridge, been impressed by it, and wondered how to make a photograph of it. When I pulled up at this spot I first intended to shoot a scene that appears to the west, but it turned out to not be quite what I imagined it might be on this morning. Ah, well – that happens! So I turned my camera in a different direction and photographed a somewhat different subject as dawn approached with some very interesting clouds in the sky to the east. As I worked on this I kept glancing up at this volcanic ridge, thinking that the clouds behind it might silhouette the trees along the skyline… but still finding the light too flat and boring. I actually made a photo or two, but wasn’t enthusiastic about it. I turned back to the other subject. A few minutes later I looked back up at this ridge and saw that the first light of early morning sun was glancing across the ridge and lighting up the Jeffrey pines that grow on its slopes. I quickly pivoted around and made a few exposures of the scene in the “good light.”
